49ers injury report: Staley sustains head injury


49ers injury report: Staley sustains head injury

GLENDALE, Ariz. -- Left tackle Joe Staley left the game in the first quarter with a head injury and did not return to the 49ers lineup Sunday against the Arizona Cardinals.When asked if Staley had sustained a concussion, 49ers coach Jim Harbaugh answered, "We'll see. You (the media) were told what his injury was, and he wasn't able to come back in the ballgame. I'm not a doctor."The 49ers did not disclose the nature of the injury, reporting it only as "head."Dr. Daniel Garza examined Staley on the sideline and walked with him back to the 49ers' locker room. Garza, assistant professor of orthopedic surgery at Stanford, is the leader of a long-term concussion study involving the Stanford football team.The NFL's protocol on concussions reads, in part:
"Once removed for the duration of a practice or game, the player should not be considered for return-to-football activities until he is fully asymptotic, both at rest and after exertion, has a normal neurological examination, normal neuropsychological testing, and has been cleared to return by both his team physician(s) and the independent neurological consultant."-- Linebacker Patrick Willis did not suit up due to a right hamstring strain that he sustained early in the 49ers' 26-0 victory over the St. Louis Rams last week. It is uncertain whether Willis will be available for the 49ers' Monday night game (Dec. 19) against the Pittsburgh Steelers. It was only the second time in Willis' career that he has not suited up for a game.
Safety Dashon Goldson said the 49ers' problems on defense were something that should not have been affected by Willis' absence."We were confident in Larry (Grant) coming in there and playing," Goldson said. "Of course, we miss Pat. He's one of our leaders and one of our playmakers on defense. But they stuck to what they were going to do. I didn't see them attacking us without Pat being there."Grant led the 49ers with nine tackles. He also broke up a pass.-- Running back Frank Gore saw a smaller percentage of snaps, as he carried just 10 times for 72 yards. Backup Kendall Hunter had eight carries for 20 yards.When asked if something was wrong with Gore, Harbaugh answered, "No, not a reason."-- Receiver Braylon Edwards played just 11 snaps after sitting out last week to rehabilitate his ailing right knee and left shoulder. Edwards did not appear pleased that his play time was limited. And Harbaugh said the team did not reduce Edwards' action due to injuries."We were doing our best to move the ball, convert, pick up those first downs and we fell short," Harbaugh said.-- Defensive end Ray McDonald sustained a left handwrist injury that required X-rays. The X-rays were believed to be negtaive, as McDonald left the locker room without any cast or wrap on his hand.-- Goldson missed one play with a right hip bruise, as he landed hard while attempting to defend Cardinals receiver Larry Fitzgerald on a down-field pass. Fitzgerald made the catch and turned the play into a 46-yard touchdown.

Report: Former No. 3 overall pick works out for 49ers


Report: Former No. 3 overall pick works out for 49ers

The 49ers appear to have plenty of depth along their front seven, but the team brought in three defensive linemen for workouts on Tuesday, according to a source.

Two of those players are Tyson Jackson, the No. 3 overall pick of the Kansas City Chiefs in 2009, and former Steelers defensive end Ricardo Mathews, reports the NFL Network. The identity of the other player was not immediately known.

Jackson has been without a team since the Falcons released him in March with two years and $8.5 million remaining on his contract. He also worked out recently with the Los Angeles Rams.

Jackson, 31, spent his first five season in Kansas City before playing three years with the Falcons. He appeared in all 16 games last season, starting seven times, and recorded 13 tackles and no sacks.

Mathews, 30, took part in his second workout with the 49ers, according to the report. A seventh-round draft pick of the Indianapolis Colts in 2010, Mathews appeared in 16 games with five starts for the Steelers last season after signing a one-year contract for the veteran minimum. He spent the previous two seasons with the Chargers. 

The 49ers have an abundance of defensive linemen, or players capable of rushing the passer from a position along the defensive line, such as DeForest Buckner, Arik Armstead, Solomon Thomas, Earl Mitchell, Elvis Dumervil, Aaron Lynch, Chris Jones, Tank Carradine, Quinton Dial, Ahmad Brooks, Eli Harold, Ronald Blair and D.J. Jones.

However, the 49ers were down three defensive linemen last week due to injuries to Buckner (ankle), Lynch (ankle) and Blair (groin). The 49ers have one opening on their 90-man roster.
