Cox will not be needed as much against Lions

SANTA CLARA -- The 49ers face offenses in the first two weeks of the season that share similar pass-first philosophies.But it does not mean the 49ers will employ the same kind of defense Sunday at Candlestick Park against the Detroit Lions that they used Week 1 at Green Bay.The Packers handed the ball off to a running back just nine times in 62 plays against the 49ers. Detroit's main running back, Kevin Smith, had 13 rushes while Matthew Stafford dropped back to pass 49 times in a 27-23 victory over St. Louis.
"They have similar personnel groupings and similar talent," 49ers defensive coordinator Vic Fangio said. "So there is some carryover."But the 49ers will not have to spend much time preparing to face a four-wideout set. Green Bay's third-receiver, James Jones, played 62-percent of the time against the 49ers. The Packers' fourth receiver, Randall Cobb, was on the field for 38 percent of the snaps.In comparison, the Lions used their third receiver, Titus Young, on only 40 percent of Detroit's Week 1 offensive plays against the St. Louis Rams. Calvin Johnson was on the field for every snap, and fellow wide receiver Nate Burleson played 80 percent of the time.Chris Culliver, the 49ers' third cornerback, played 90 percent of the snaps against the Packers. He figures to again see a lot of action against the Lions.Perrish Cox, the 49ers' fourth cornerback, was in on 76-percent of the plays. Cox mostly replaced linebacker Patrick Willis in the 49ers' "dime" defense, which calls for six defensive backs. This week, Cox figures to see a dramatic reduction in play time, as the Lions will use two tight ends as much as they play three wide receivers."I just prepare for the most and prepare for the best, the most difficult," Cox said. "If it is less reps it'll be more just going all out and give it 100 percent and do whatever I can."Last week, Cox matched up mostly against Cobb, who lined up in the backfield. Cobb caught all nine passes from Aaron Rodgers that came his way, but he averaged just 8.6 yards per reception."He did well," Fangio said of Cox. "He played a lot of plays. He did a good job. There were things he could've done better and, hopefully, will do better."Cox said he could have been more physical with Cobb. Also, Cox overran a couple tackles out of habit from playing cornerback."I'm used to, at the corner position, rallying to the ball and cutting everything back in to my help," Cox said. "But (in that defense) I am the linebacker. I am the inside help."

Large report finds CTE in 110 of 111 brains from former NFL players


Large report finds CTE in 110 of 111 brains from former NFL players

CHICAGO -- Research on 202 former football players found evidence of a brain disease linked to repeated head blows in nearly all of them, from athletes in the National Football League, college and even high school.

It's the largest update on chronic traumatic encephalopathy, or CTE, a debilitating brain disease that can cause a range of symptoms including memory loss.

The report doesn't confirm that the condition is common in all football players; it reflects high occurrence in samples at a Boston brain bank that studies CTE. Many donors or their families contributed because of the players' repeated concussions and troubling symptoms before they died.

"There are many questions that remain unanswered," said lead author Dr. Ann McKee, a Boston University neuroscientist. "How common is this" in the general population and all football players?

"How many years of football is too many?" and "What is the genetic risk? Some players do not have evidence of this disease despite long playing years," she noted.

It's also uncertain if some players' lifestyle habits - alcohol, drugs, steroids, diet - might somehow contribute, McKee said.

Dr. Munro Cullum, a neuropsychologist at UT Southwestern Medical Center in Dallas, emphasized that the report is based on a selective sample of men who were not necessarily representative of all football players. He said problems other than CTE might explain some of their most common symptoms before death - depression, impulsivity and behavior changes. He was not involved in the report.

McKee said research from the brain bank may lead to answers and an understanding of how to detect the disease in life, "while there's still a chance to do something about it." Currently, there's no known treatment.

The strongest scientific evidence says CTE can only be diagnosed by examining brains after death, although some researchers are experimenting with tests performed on the living. Many scientists believe that repeated blows to the head increase risks for developing CTE, leading to progressive loss of normal brain matter and an abnormal buildup of a protein called tau. Combat veterans and athletes in rough contact sports like football and boxing are among those thought to be most at risk.

The new report was published Tuesday in the Journal of the American Medical Association.

CTE was diagnosed in 177 former players or nearly 90 percent of brains studied. That includes 110 of 111 brains from former NFL players; 48 of 53 college players; nine of 14 semi-professional players, seven of eight Canadian Football league players and three of 14 high school players. The disease was not found in brains from two younger players.

A panel of neuropathologists made the diagnosis by examining brain tissue, using recent criteria from the National Institute of Neurological Disorders and Stroke, McKee said.

The NFL issued a statement saying these reports are important for advancing science related to head trauma and said the league "will continue to work with a wide range of experts to improve the health of current and former NFL athletes."

After years of denials, the NFL acknowledged a link between head blows and brain disease and agreed in a $1 billion settlement to compensate former players who had accused the league of hiding the risks.

The journal update includes many previously reported cases, including former NFL players Bubba Smith, Ken Stabler, Dave Duerson and Ralph Wenzel.

New ones include retired tight end Frank Wainright, whose 10-year NFL career included stints with the Miami Dolphins, New Orleans Saints and Baltimore Ravens. Wainright died in April 2016 at age 48 from a heart attack triggered by bleeding in the brain, said his wife, Stacie. She said he had struggled almost eight years with frightening symptoms including confusion, memory loss and behavior changes.

Wainright played before the league adopted stricter safety rules and had many concussions, she said. He feared CTE and was adamant about donating his brain, she said.

"A lot of families are really tragically affected by it - not even mentioning what these men are going through and they're really not sure what is happening to them. It's like a storm that you can't quite get out of," his wife said.

Frank Wycheck, another former NFL tight end, said he worries that concussions during his nine-year career - the last seven with the Tennessee Titans - have left him with CTE and he plans to donate his brain to research.

"Some people have heads made of concrete, and it doesn't really affect some of those guys," he said. "But CTE is real."

"I know I'm suffering through it, and it's been a struggle and I feel for all the guys out there that are going through this," said Wycheck, 45.

In the new report, McKee and colleagues found the most severe disease in former professional players; mild disease was found in all three former high school players diagnosed with the disease. Brain bank researchers previously reported that the earliest known evidence of CTE was found in a high school athlete who played football and other sports who died at age 18. He was not included in the current report.

The average age of death among all players studied was 66. There were 18 suicides among the 177 diagnosed.

Aquan Boldin is looking for a new football home.

And the former 49ers wide receiver is visiting with the Bills on Monday, according to multiple reports.

Boldin started all 16 games with the Lions last season, recording 67 catches for 584 yards and eight touchdowns.

From 2013 to 2015 with the 49ers, he racked up 237 receptions, 3030 receiving yards and 16 touchdowns.

The three-time Pro Bowler will turn 37 years old in October.

Boldin entered the NFL as the 54th overall pick in the 2003 draft.
