Both suffered knee injuries in last Sunday's AFC divisional playoff game against Indianapolis and underwent tests Monday. Tomlinson has a hyperextended left knee and Rivers a sprained MCL in his right knee.
"I think I'll definitely be able to play," Tomlinson said Monday of the AFC championship game. "They have me listed as questionable. But I'm pretty sure I'll be able to play."
Chargers Coach Norv Turner said Rivers probably won't practice until late in the week.
Tomlinson did not play in the second half of the Chargers' 28-24 victory over Dallas. Rivers was hurt on a touchdown pass to Darren Sproles at the end of the third quarter. Although he was not hit on the play, Rivers limped off the field and did not return.
