Robinson (groin) did not practice Wednesday, Mike Chappell of IndySportCentral.com reports.

Robinson missed the Colts' Week 11 game against the Titans but made it back in time for the team's Thanksgiving Day tilt against the Steelers. While it's unclear if he suffered a setback, his participation in practice throughout the remainder of the week hopefully will provide a clue toward his availability for Monday night.
