As he forecast yesterday, cornerback Carlos Rogers was on hand for the start of 49ers practice. However, another starter, outside linebacker Ahmad Brooks, was not present. Brooks, Justin Smith and Jonathan Goodwin were not seen at the start of practice. Smith and Goodwin, two of the 49ers' most veteran players, typically are given Wednesdays off.
Also not practicing today is fullback Will Tukuafu. He was seen working out on a side field with a trainer while wearing a brace on his left knee. Tukuafu is believed to have suffered a Grade 1 sprain of his MCL in the first quarter Sunday. His availability for the upcoming game against the Seahawks will be determined later this week.
Receiver Michael Crabtree suffered a shoulder injury on the second play of Sunday's game. Crabtree seemed to be affected by it early, but he looked better as the game went on. He was at practice today and - from afar, at least - seemed fine.
Defensive coordinator Vic Fangio has said in the past that a starting player has to be near 100 percent for him to resume his spot in the lineup. Asked today if Rogers gets his former spot back if he is healthy enough to play, Jim Harbaugh seemed to dance around the question.
"You can't just - there's a subset of questions other than the question, 'Will Carlos start if he's ready to play?'" Harbaugh said. "In terms of do you come back at 100 percent, 90 percent, 95 percent, that all will be determined on the practice field, those subset of questions will be answered out there."
The 49ers will release the practice report -- and presumably reveal why Brooks is missing -- later this afternoon.
