LOS ANGELES -- USC interim head coach Ed Orgeron had plenty to smile about on Wednesday evening.
When he surveyed the practice field, there was Marqise Lee, although limited, participating in team drills.
Orgeron was asked if seeing Lee run around on the practice field brightened the team's mood.
"It brightens mine," he said. "I didn't ask them if it brightens theirs but it sure brightens mine."
It was the first time Lee practiced all week since missing the team's game against Utah last Saturday. It was the second time in three games Lee was out of the lineup with a knee injury.
Orgeron announced following practice that Lee was upgraded to probable for Friday's game at Oregon State.
Lee suffered a knee injury on Sept. 28 at Arizona State. The team played just three games in the month of October and Lee missed two of them. In that lone game, he caught two passes for 18 yards in the loss at Notre Dame.
Despite missing time, Lee is still leading the team with 32 receptions and is second on the team in receiving yards with 403.
In addition to Lee, tight end Xavier Grimble was also upgraded to probable, which helps a tight end unit that was without all three scholarship tight ends last week against Utah.
Walk-on Chris Willson and defensive end/outside linebacker turned tight end for the second time this season, Kevin Greene, are expected to see action there.
With the depth concerns at wide receiver and tight end, the school announced the addition of two more walk-ons early Wednesday. David Mellstrom is a junior wide receiver and former walk-on at Virginia Tech. The other walk-on, Robert Flewelling out of Maranatha High School, is listed as a wide receiver and tight end.
Perhaps, Lee and Grimble's return to the lineup can give USC a boost in a land where they haven't won since 2004.
"We take it day by day here," Orgeron said. "We'll see."
