USC kicker Andre Heidari reportedly underwent knee surgery last week to repair a torn meniscus in his knee.

The sophomore kicker did not accompany the team on its latest road trip to Syracuse. Walk-on freshman kicker Alex Wood assumed kicking duties for the Trojans, converting on all six extra point attempts in USC's 42-29 victory.

Heidari originally hurt the knee in the season opener against Hawai'i. With USC not disclosing any information on injuries anymore, Heidari's absence had been a little cloudy up until this point.

With the Trojans' starting kicker injured, this could put a serious dent in USC's special teams' play moving forward. Heidari converted on 15-of-17 field goal attempts as a freshman last year, while also nailing all 50 PAT attempts.

And in the past, a field goal has been the difference between a win and a loss for USC.

It will be interesting to see how Kiffin decides to use Wood going forward for the next couple weeks, especially with USC on the road for its next three of four games (at Stanford, vs. California, at Utah, at Washington).
