Two big pieces of the Indianapolis Colts offense in wide receiver T.Y. Hilton and running back Marlon Mack returned to practice Thursday as the team prepares for the Week 13 road matchup with the Jacksonville Jaguars.

Hilton, who is dealing with a groin injury, popped up on the injury report Wednesday, while Mack suffered a concussion during the Week 12 win over the Miami Dolphins.

Both were able to return to practice on Thursday along with safety Clayton Geathers, who seemed to have a precautionary day off Wednesday.

The Colts offense has been rolling throughout this five-game winning streak and both Hilton and Mack have had a large say in the unit’s success.

Mack still seems to be in the league’s concussion protocol and while it remains to be seen if he will play Sunday, it does appear he’s making progress.

The Jaguars defense may not be the formidable unit it was a year ago when they reached the AFC Championship game, but the Colts will need Hilton and Mack if they want to prove their dominance.

The Colts will release an injury report Thursday before the designations come out on Friday ahead of the weekend.
