Indianapolis Colts All-Pro linebacker Shaquille Leonard returned to practice Wednesday, albeit wearing a red non-contact jersey.

Leonard has been sidelined since suffering a concussion and injuring his nose in his Week 4 season debut against Tennessee.

Leonard has yet to play a full game in 2022. He had offseason back surgery that kept him out of the first three games.

Leonard, 27, made two tackles and played 16 snaps in the loss to the Titans before colliding with teammate Zaire Franklin in the second quarter. Leonard broke his nose in addition to sustaining a concussion and exited the game.

Colts coach Frank Reich said the nose injury was "significant" and required surgery.

It's unclear if Leonard, who is still in the concussion protocol, will be ready to play this week. The Colts (3-2-1) host the Titans (3-2) in their second and final meeting of the regular season. Tennessee won the first matchup 24-17.

"A lot of discussion on that over the last 48 hours,'' Reich told reporters. "How much time is he going to need? Is it going to take a week? Two weeks? We're going to need to see that. That's a collective ‘We are going to need to see that.'"

The three-time Pro Bowl selection and three-time All-Pro has piled up 538 tackles and 15 sacks in 58 games over his first four seasons. He also has 17 forced fumbles and 11 interceptions.
