"It's nothing serious, just a hyperextension," Tomlinson said. "I think they've got me listed as questionable, but I'm pretty sure I'll be able to play. Obviously, I'm going to do all I can to practice. I don't want to miss any time to practice."
Tomlinson carried only seven times, for 28 yards, and caught one pass for 20 yards. He's rushed for just 70 yards in San Diego's two playoff wins.
Tomlinson and Rivers said on Sunday that they felt they could have gone back in if needed. But Norv Turner said it was a medical decision to keep Tomlinson on the sideline.
"He couldn't have gone in, is the way I understand it," Norv Turner said.
