Indianapolis Colts wide receiver Austin Collie is not expected to play today against the Dallas Cowboys, ESPN's Adam Schefter reports.

Collie is still suffering the effects of a concussion he sustained in Week 11 against the New England Patriots.

That concussion, Collie's second of the season, kept him on the sidelines for last week's 36-14 loss to the San Diego Chargers and had him listed as "questionable" for today's game against Dallas.
