Morning 49ers nuggets

SANTA CLARA, Calif. – San Francisco 49ers defensive coordinator Vic Fangio said cornerback Tarell Brown will be eased back in to the playing rotation when he returns from the rib injury he suffered at New Orleans on Nov. 17. Brown has been practicing on a limited basis this week. Tramaine Brock took his place.

There is a chance Brock, who recently signed a four-year contract extension, will stay the starter, since he is in the team’s long-term plans and has played well in Brown’s spot.

Rookie tight end Vance McDonald practiced on a limited basis Thursday after sitting out Wednesday’s workout with an ankle injury. He should be able to play Sunday.

Offensive coordinator Greg Roman said receiver Michael Crabtree has no soreness from his Achilles injury and has looked good in practice this week. Crabtree made his season debut Sunday and played 42 snaps against St. Louis.

Are the 49ers uptight going into a big game against Seattle? It didn’t look like it Thursday. Quarterback Colin Kaepernick, linebacker NaVorro Bowman and receiver Quinton Patton had a punting contest before practice. On my unofficial scorer’s card, it was Kaepernick in a landslide.

Speaking of Kaepernick, Roman had this to say about the quarterback's performance against the Rams: “I thought last week’s game against the Rams was one of the best games, if not the best, he’s played big-picture-wise. Everything from soup to nuts, A to Z, I thought it was a magnificent performance on a lot of levels.”

Kaepernick wasn’t the only quarterback getting praise. Seattle's Russell Wilson got a strong endorsement from Fangio: “Everybody thinks this guy’s a freak quarterback. This guy’s just a really good quarterback who happens to be very fast, very quick and very elusive. He’s not just a guy that runs around. He’s a passer, too. He can run any offense and be a confident quarterback.”

Finally, 49ers fans may not want to look up Sunday when the Seahawks come to town.
