Westbrook-Ikhine was signed to the Colts' practice squad Monday, Mike Garafolo of NFL Network reports.
Westbrook-Ikhine was let go by the team Sunday, but he'll remain in Indianapolis ahead of the regular season. With Alec Pierce (ankle) still uncertain for Week 1, it's possible that Westbrook-Ikhine will be elevated to the active roster for the team's matchup with the Ravens on Sept. 13.
