INDIANAPOLIS — The Indianapolis Colts believe lingering pain in Andrew Luck's lower left leg will likely force their starting quarterback to miss the rest of the preseason.
They're still unsure about his availability for the Sept. 8 season opener against the Los Angeles Chargers.
Colts general manager Chris Ballard said Tuesday additional testing revealed Luck appears to be suffering from an injury near the front of his ankle, something his previously diagnosed strained left calf might have exacerbated.
"Honestly, I think it's a cumulative thing through the years. Andrew's had some issues with his left (ankle) for a while, so I think it's really a cumulative thing," Ballard told local reporters on a conference call.
