Will Tukuafu day-to-day with knee injury

The San Francisco 49ers' injury watch this week will not be relegated to cornerback Carlos Rogers. Fullback Will Tukuafu's health is also in question as the 49ers prepare to play at Seattle in the NFC title game on Sunday.

The 294-pound Tukuafu left the win against Carolina on Sunday with a knee injury. Monday, 49ers coach Jim Harbaugh said he was encouraged by Tukuafu’s movement. He had an MRI Monday. A source with knowledge of the situation said Tukuafu is day-to-day, but there is no precise recovery time.

So, it is unclear if Tukuafu can play. Because the 49ers lean on the conservative side when it comes to injuries, the odds could be against Tukuafu playing Sunday. It will probably be a game-time decision.

Tukuafu was splitting time with Anthony Dixon after Bruce Miller was lost for the season in December with a broken scapula. Dixon and tight end Vance McDonald, who took over Tukuafu’s role, will play Sunday if Tukuafu can’t.

For Rogers, Wednesday will be key. The cornerback has missed the past two games with a hamstring injury he suffered in Week 17. He hasn’t practiced since. Rogers and the team have said the injury isn’t overly serious, yet he has not been able to get on the practice field. If he can practice this week, he can probably play at Seattle. Perrish Cox has taken his place as the nickel cornerback.
