Gay said Wednesday that he underwent a procedure to address a sports hernia following the Colts' final preseason game Aug. 22, Kevin Bowen of 107.5 The Fan Indianapolis reports.
As a result, Gay doesn't know if he'll be available for Sunday's season opener against Houston, according to Joel A. Erickson of The Indianapolis Star. If the veteran kicker ends up sidelined this weekend, the Colts have the option of elevating practice-squad member Spencer Shrader ahead of the Week 1 contest.
