adjustment

USC sophomore defensive lineman Jahkeem Stewart, who was spotted over the weekend sporting crutches and a boot on his injured right foot, is expected to miss the Trojans’ season opener against San Jose State, coach Lincoln Riley said.

Losing Stewart for longer than that would be a bitter pill for USC to swallow at the start of a highly anticipated season. But while reports have suggested that Stewart is likely to miss USC’s entire nonconference slate with the injury, Riley suggested Tuesday that he could debut as soon as the following Friday, when USC takes on Fresno State in its second game of the season.

“What he’s dealing with right now is minor,” Riley said. “The plan is to probably hold him and I think he’ll be able from that point forward. But it’s certainly not long term. A little precautionary right now.”

Stewart played through a stress fracture in his foot throughout his freshman season after suffering the injury in August. He missed the season opener then as well, but elected not to have surgery, in order to keep contributing to the team.

“I could have got surgery, but I wouldn’t have felt comfortable,” Stewart said earlier this month. “I wouldn’t have felt complete as a human, knowing that I still had stuff in the tank that I could have gave to my team.”

Stewart ended up getting surgery on his foot in December. But when Stewart spoke to reporters during camp, he said his foot felt “1,000%”

But the concern now, as Stewart continues to deal with a foot issue, is whether this injury could continue to linger beyond just a game or two of his sophomore season.

Riley was not sounding that alarm Tuesday. But he also didn’t rule out the possibility that USC may be managing the situation throughout this season.

“We just gotta watch it,” Riley said. “Everybody is different in terms of their size, their biomechanics in terms of how they run and especially guys like Jahkeem who are pretty violent in the way they move and transfer energy on the ground — like there’s some force going into the ground. So yeah, I think some of these injuries are freak things that happen from time to time in this game, that’s part of it. And then there are things that as guys go, and as their bodies evolve and get bigger and stronger, you have to make adjustments on and they have to make adjustments on.”

USC was especially cautious with Stewart’s injury during the week last season, which led Stewart to sit out a significant number of practices. He still played in 11 games, missing the opener and the bowl game. But on average, Stewart played just 21 snaps per game as a freshman.

He was still named a freshman All-American, in spite of the difficult circumstances. All signs pointed toward him taking a major leap as a sophomore.

This latest injury could throw a wrench in that. But Riley expressed confidence in the depth of USC’s defensive interior, which was not something he could’ve said even this time last year.

“We’ve had some young guys emerge in that room, especially who are going to command some looks and some opportunities to play and go prove themselves on Saturdays here right away, and then you combine it with the experience we have in that room,” Riley said.

“We’ll have a good healthy rotation and be able to withstand any dings along the way.”

USC coach Lincoln Riley said he is glad to have the Trojans’ annual rivalry game with Notre Dame back without compromising the Trojans’ biggest need.

The schools announced they agreed to a four-year series starting in 2030 during Week 1 of the season at the Coliseum. The following year the teams will play in Week 1 at Notre Dame Stadium. The 2032 and 2033 games will be played during Week 1-3 of the season.

“We felt like the best thing for our program was to play this game early in the season,” Riley said. “As I’ve said publicly, we’re a part of a conference. We have a conference schedule to answer to. We don’t make our own schedule, we don’t choose our own kickoff times. And so with that, we have much less flexibility and so it made more sense for us to play this game in a traditional nonconference window.”

Riley, who took many jabs locally and nationally for letting one of college football’s most prestigious rivalry series expire, has been steadfast in noting the inequity between USC playing Notre Dame amid a grueling Big Ten schedule and independent Notre Dame’s ability to surround the contest with less taxing matchups to aid its College Football Playoff push.

Ultimately, both schools said they valued the rivalry and they found a way to reach an agreement announced Monday.

USC owns a 37-53-5 all-time record against Notre Dame, excluding the Trojans’ 2005 victory, which was later vacated due to NCAA sanctions (original record: 38-53-5). Riley is 1-3 during his Trojans tenure against the Irish. The teams battle for the Jeweled Shillelagh.

“I think this benefits everyone,” Riley said. “I think this benefits USC. I think this benefits Notre Dame. I think this benefits college football. This is important. We know its important to our fan base, we know it’s important to alumni, we know it’s important to former players and coaches.”
