Andrew Luck reportedly is expected to join Colts practice on a limited basis within days, which could lead to his return to action as early as Week 5.

ESPN reported Sunday that sources say the Colts quarterback "is expected to begin practicing as early as this week." He said that sets the stage for Luck's return to the starting lineup somewhere between Weeks 5 and 7.

Luck's recovery from offseason shoulder surgery has been the dominant storyline since the Colts began training camp, with coach Chuck Pagano growing visibly tired of answering questions about Luck's projected return.

ESPN reports that sources indicate Luck's recovery has been especially "noticeable and encouraging" since he recently consulted with Saints quarterback Drew Brees, who had similar surgery in 2006. Luck also reportedly met with Brees' physical therapist, Dr. Kevin Wilk.

The Colts are 0-2 in Luck's absence, with Scott Tolzien and Jacoby Brissett at quarterback. They've scored only 22 points through two games.
