Mack appears on track to sit out Saturday's preseason game against the Bears after coach Frank Reich indicated that most of the Colts' starters won't play in the contest,Mike Wells of ESPN.com reports.
Per the report, it wasn't an easy call for Reich to make, but given that most of the Colts' key starters were in his system last season, the team appears ready to err on the side of caution this weekend. Franchise quarterback Andrew Luck (calf/ankle) was already set to miss the exhibition slate, which may influenced Reich's decision to rest Mack and the Colts' other core pieces.
