LOS ANGELES — Center Kristofer O’Dowd expects to play for No. 4 Southern California in its game at No. 6 Ohio State on Saturday.

O’Dowd practiced with the Trojans on Monday after missing last weekend’s season opener against San Jose State to rest his dislocated kneecap. The junior is considered to be among the nation’s top centers, and is a key component of an already powerful USC offensive line.

O’Dowd says he’s ‘‘definitely going to be back for this game,’’ but coach Pete Carroll says he won’t agree until he sees how O’Dowd does in Tuesday’s practice in pads.

Defensive tackle Averell Spicer practiced with the Trojans after missing the opener with a sprained ankle. Spicer also hopes to play Saturday in Columbus.
