Brown does not shrink from 'Megatron' challenge

Calvin Johnson is six feet, five inches and 236 pounds of touchdowns and receiving yards. His speed and strength earned him the moniker 'Megatron' as well as 16 scores and 1,681 yards in 2011.There are defensive backs who may be faster, but none bigger. The tallest DB on the 49ers roster is safety Dashon Goldson at 6-2. The heaviest is Donte Whitner at 208 pounds. Tarell Brown (5-10, 193) and Carlos Rogers (6-0, 192) are typical in size for starting corners.Those kind of disparities certainly give Johnson the advantage over his defenders, and that's just the kind of challenge Brown is looking for."I always get geeked up for games like this because our backs are up against the wall," Brown said. "People don't expect you to play up to your caliber just because of the type of guy he is. For me, I'm really excited."Excitement is one thing. Execution is another. Johnson will pose a challenge Sunday especially when the quarterback getting him the ball threw for more than 5,000 yards last season. But as good as Matthew Stafford is, Johnson is key to containing the Lions offense. Brown explained how best to do it."I think the biggest thing is really to key Johnson more or less, with him getting in and out of his breaks," Brown said. "You want to take the focus off the quarterback and have more focus onto him and kind of see what his types of stems are, where he likes to go with the ball, the types of routes he likes and how he bends and breaks out of his cuts."A lot of that information will come from film study, some from instinct and a good amount from a player's 'tells'. Like a bad poker player who gives away his hand by showing emotion, a receiver can tip off a defender.RELATED: Calvin Johnson misses Lions' Wednesday practice
"The receiver's eyes usually get big. They get wide-eyed just because the ball is coming and you pretty much, you hear the crowd as well," Brown said. "So when you hear the crowd kind of 'oohing' and 'ahhing' you know the ball is coming to you and you're in attack mode."With a guy like that the hardest thing is the jump ball. You want to get in to him. Be aggressive with him at the line of scrimmage. My biggest thing is when the ball is in the air we're both going to compete for the ball. He might have a height advantage, but if I get off the ground quicker than him I feel like I'm taller than him. For me, I'm going to go out and compete with him."

Staley sits out 49ers practice with hamstring injury

Staley sits out 49ers practice with hamstring injury

SANTA CLARA – Left tackle Joe Staley, who has not missed a game since 2010, did not practice Thursday due to a hamstring injury.

The 49ers’ five-time Pro Bowl performer has the third-longest active streak among offensive tackles with 92 consecutive starts. Only Cleveland's Joe Thomas (156) and Oakland's Donald Penn (152) have started more consecutive games.

Staley’s availability for Sunday’s game against the New York Jets at Levi’s Stadium is in question after he was held out of practice on Thursday after going through the full workload on Wednesday.

If Staley is unable to play, the 49ers would likely move left guard Zane Beadles to left tackle and insert Andrew Tiller at left guard. Tiller started the first five games of the season at right guard before rookie Joshua Garnett took over.

Pearl Harbor speech: Admiral calls out Kaepernick, others for anthem kneeling

Pearl Harbor speech: Admiral calls out Kaepernick, others for anthem kneeling

Wednesday was the 75th anniversary of the attack on Pearl Harbor.

Although he didn't call out Colin Kaepernick by name, Admiral Harry B. Harris gave a speech that included a message intended for a certain group of athletes and/or entertainers.

“You can bet that the men and women we honor today, and those who died that fateful morning 75 years ago, never took a knee and never failed to stand whenever they heard our national anthem being played."

Many of those in attendance gave the Admiral a standing ovation.

During the preseason, Kaepernick remained seated on the 49ers' team bench during the national anthem.

After sparking a national controversy, Kaepernick began kneeling as opposed to sitting.

After the 49ers' loss to the Bears on Sunday, Kaepernick said he will continue his demonstration moving forward.

"Today we have a precious opportunity to reflect -- to reflect on what it means to be a patriot, to reflect on what it means to be a nation tested by war, and to reflect on both the costs and the blessings of liberty," Admiral Harris added. "To America's World War II patriots here and watching at home -- we will never forget your courage under considerable fire and seemingly insurmountable odds.

"Because of you, our future remains bright. We owe you an immeasurable debt and we can't thank you enough for answering the call of duty when Lady Liberty needed it the most."
