INDIANAPOLIS – For the first time in a month, the No. 30 helmet and pads of LaRon Landry rested inside his locker on Thursday.

Landry, back from a four-game suspension, was a full participant at Thursday's practice. The Colts first practice of the week occurred on Thursday with the team taking center stage on Monday Night Football this week.

Both Chuck Pagano and Ryan Grigson have said that the Colts will evaluate Landry throughout the week to decide whether or not to bring the safety back up to the 53-man roster before Monday night's matchup.

"We have the exemption on him this week. We can take it off at any time up until Monday," Grigson said before Thursday's practice.

"Just like all the players, we have to scrutinize and look at (Landry) from every angle, see where his legs are at. Today's our first real day of practice, and (we will) just kind of take it from there and have those discussions. We'll take it day-by-day."

Landry took to the Colts practice field on Thursday and looked like the physical natured safety his teammates are used to seeing.

In Landry's absence, Sergio Brown has slid into the starting role, teaming up with veteran Mike Adams at the back end of the Colts defense.

The safety position had a ton of questions all offseason long and now it heads into the second half of the year with some much-needed depth.

"To get (Landry) back is a great benefit to our defense and what he brings," D'Qwell Jackson said after watching Landry practice on Thursday.

"He's a hitter and plays with a lot of passion. It's great to have him back. Sergio has been doing a great job. Mike has been doing a great job. (Landry) just adds to that depth and it's going to be good moving forward."

After Thursday's practice, Pagano said Landry looked "good."

The Colts will continue to assess things with Landry as practice spans through Saturday to see whether or not they will make a move on their 53-man roster.

"If (Landry's) ready to play on Monday, then we've got to do it by 4 p.m, (Monday)," Pagano said earlier this week explaining the exemption rule. "If he's not and we don't feel like we want to throw him out there with him being gone for a month, which I hope everybody would understand, then we don't have to do that."

If Landry doesn't play Monday, the Colts will have to make a corresponding roster move on Tuesday (11/4).

The Colts are on a bye next week before New England comes to town on November 16.
