Sharpe will miss at least six weeks with a left hamstring strain, Brett Siegel of ClutchPoints.com reports.
Sharpe had been poised to enter the season as the top backup to starting center Nic Claxton, but his hamstring injury will likely keep him out until at least the second half of November. With Sharpe out of the mix, Noah Clowney could see increased run on the second unit to open the season, while Claxton's minutes floor could be higher.
