CHARLOTTE, N.C. (AP) - San Francisco 49ers fullback Will Tukuafu left in the first quarter of Sunday's NFC divisional playoff game at Carolina because of an injured left knee.
The 49ers said he's done for the day.
Tukuafu was hurt on the opening series after catching a short pass in the flat from Colin Kaepernick. As Panthers defensive back Captain Munnerlyn pulled him down, Tukuafu's left leg bent awkwardly beneath him as he hit the turf.
Tukuafu was down briefly before eventually walking to the sideline. He was initially questionable to return, but was ruled out by the end of the first quarter.
