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.
