After two successful extra points, USC Trojans kicker Andre Heidari is out of the game with an apparent injury to his right leg. Replacing the kicker on the field will be walk-on redshirt sophomore, Chris McMahon, although the Trojans may not rely on McMahon for an extra point.
Instead, without their starting kicker, USC may continue their trend of going for a two-point conversion following a touchdown as they have on each of their last two scores. Following those scores, though, it was Heidari kicking off for the Trojans.
Where McMahon's impact will likely be seen during the remainder of the game is during kickoffs as he's slated to fill in for Heidari in that role. The severity of Heidari's injury and a timetable for his return are unknown right now.
