Robinson (concussion) did not play in Thursday's preseason game, ESPN reports.
EDGE Analysis
It's not clear if Robinson will be ready for the start of the regular season. The Colts could be thin at running back behind Frank Gore with both Dan Herron and Vick Ballard suffering injuries in Thursday's preseason game. Robinson showed enough of a spark in the preseason that he could eventually be the No. 3 or No. 2 running back if healthy.
