Andrew Luck will likely miss the rest of the preseason with an injury near the front of his left ankle.

Colts general manager Chris Ballard says he isn’t sure if the injury will keep Luck out of the Sept. 8 season opener against the Los Angeles Chargers.

“We’re three and a half weeks away from regular season, so I’m not ready to say (Luck’s regular-season opener is in jeopardy),” Ballard told reporters on a conference call Tuesday night.

Indy’s starting quarterback has been dealing with lower leg pain since straining his left calf in March. Luck missed all of the team’s offseason workouts and has not participated in any full-team drills at training camp.

Ballard spoke to local reporters on a conference call after team owner Jim Irsay told SiriusXM that the Colts believed Luck had injured a small bone near the back of the ankle. But Ballard says additional testing determined the bone was not the cause of Luck’s pain.

Former NFLer Chad Ochocinco had an, um, unconventional thought on what could help Luck heal up quickly, though it probably wouldn’t gain him many friends in the locker room.
