Colts' Pagano reiterates no timeline for Luck's return

With the regular season rapidly approaching, fans of the Indianapolis Colts have ample reason to be worried about their prospects.

Colts head coach Chuck Pagano is unsure when Andrew Luck will be available, seven months after the star quarterback underwent shoulder surgery.

"There's no timeline," Pagano said via Stephen Holder of The Indianapolis Star.

Pagano said the Colts wouldn't be able to accurately assess Luck's recovery until he takes the field, but he's yet to have been cleared by the team's medical personnel.

"We're not going to know until we get him out here,” Pagano said. "When the doctors say he's ready and he’s 100 percent and he can start practicing, then we’ll have that answer."

Luck has been the central pillar of the franchise since being selected first overall in the 2012 NFL Draft, and any missed time during the regular season would be a catastrophic proposition for the Colts.

If Luck is unavailable for the season opener, Scott Tolzien would likely become the starter, a nearly untenable position for the Colts if they are to snap a two-year playoff hiatus.
