Overview

• Johnson re-aggravated a knee injury during USC’s 33-17 win over Purdue, and Riley confirmed Tuesday he will miss the rest of 2025.
• The sophomore transfer arrived from UCF with expectations to contribute after logging 452 defensive snaps as a freshman there.
• His 21 snaps against Purdue were his most at USC, and his season ends with one tackle.
• USC’s cornerback rotation has been in flux, with DeCarlos Nicholson steady at the top as DJ Harvey, Braylon Conley, and Marcelles Williams cycle through starts.
• Depth is further strained as Conley exited with a wrist issue and Prophet Brown and freshman RJ Sermons remain sidelined, pressing immediate next-man-up moves.
