LOS ANGELES — A year ago, Anthony Lucas was better in practice than he was in actual football games. A year later, during USC’s fall camp, a confidence steadily built that these Trojans wouldn’t only see the best version of him on Howard Jones Field. “It feels a bit different,” head coach Lincoln Riley said a month ago, of Lucas. “More mature. More steady.” Through six games in 2024, USC has gotten the version of Lucas the coaches first envisioned when they plucked a 6-foot-5, 295-pound former five-star recruit out of the transfer portal from Texas A&M in 2023. Beefed back up to 275 pounds after slimming as a sophomore, Lucas quickly established himself as USC’s most important defensive line piece, racking up a team-high 12 pressures and proving stout against the run off the edge. But they only had that different version, it turns out, for six games, as Riley told reporters on Tuesday that Lucas would be out for the rest of the season after undergoing a procedure on his leg. Lucas had limped off with an injury and was taken to the medical tent late in USC’s Week 5 loss to Minnesota, still managing to play 38 snaps and record six tackles against Penn State last weekend, according to Pro Football Focus. He wasn’t seen working with USC’s defensive line group during the early period of USC’s practice on Tuesday, however, and Riley clarified that Lucas had an an injury to a “lower extremity.” “Hate it for Anthony, because he’s really improved,” Riley said. “He had a really strong impact on our defense.” “He’s in a good frame of mind,” Riley continued. “We’ll be excited to get him back next year and get him rolling and build on all the progress he made. And in the meantime, it’s going to create an opportunity for some more guys to step up.” The question is who, exactly, as USC’s defensive line room is already dangerously thin – and its front was further weakened Tuesday by the announced medical redshirt of senior linebacker Eric Gentry. Lucas was praised throughout the fall for his versatility in rotating at interior and edge spots, and both groups will feel his loss, a junior who has played more snaps than anyone else on the Trojans’ defensive line in 2024. Starting defensive tackle Gavin Meyer is banged up, carted off midway through last the loss to Penn State. Former difference-maker Bear Alexander is out of sight and out of mind, not seen at a USC practice since settling on a redshirt three weeks ago. “You rely on the development that’s been going on (behind) the scenes, and the guys that you’ve recruited,” Riley said, when asked the plan for USC’s defensive line with Lucas’ absence. “And maybe there’s some guys that you thought, ‘Well, maybe their role won’t be quite as much this year, maybe they redshirt’ – that, now all of a sudden, they’re going to have that opportunity.” Related Articles College Sports | USC linebacker Eric Gentry announces he’ll redshirt after ‘series of concussions’ College Sports | Analysis: With CFP hopes dashed, USC should look to youth development College Sports | Swanson: Maybe we expected too much from USC?

He flashed college-ready burst during a handful of snaps against Utah State in Week 2, recording a few tackles and a quarterback pressure, and stands to inherit a few looks during the second half of USC’s season. “From spring to now,” defensive coordinator D’Anton Lynn said of Fountain in early September, “he’s like a different player.” USC, too, will desperately need established names in its edge group to step up in Lucas’ absence, as the roster has continued to rank dead-last in the Big Ten in quarterback pressures for much of this season. Sophomore Braylan Shelby has been stout against the run, but after putting on 20 pounds during the offseason, he has recorded just one sack and five quarterback hurries through six games. “Probably higher than anybody on the team,” defensive ends coach Shaun Nua said during fall camp, when asked the standard for Shelby in 2024. “Just as high,” he continued, “same as Anthony Lucas, and any guy that has the ability to do big things.”
