On Thursday, the Indianapolis Colts continued their week of preparation for this weekend's matchup with the Baltimore Ravens.

The injury report continues to show positive signs, with three players upgraded from Wednesday's report and only one player, defensive tackle Grover Stewart, missing practice for a scheduled rest day. Stewart also had rest days on Thursdays last season.

The Ravens also received a positive update on their Thursday report, although they conducted a walkthrough rather than a normal practice.

Here is how both teams' health is shaping up ahead of Sunday afternoon's matchup.

Haulcy, Ogletree, and Van Pran-Granger were all boosted to full participation from Wednesday's limited status. Haulcy hadn't practiced for two weeks beforehand, and Van Pran-Granger missed his first week of practice with the team last week after he was acquired in a trade.

Richardson was a new addition to the injury report on Thursday with an illness, but was a full participant.

Although Pierce logged a full participation last week, the Colts are limiting him this week, but the plan is still for him to play on Sunday. The Colts will normally do what they can to not overload a player returning from injury.

There is not yet any indication that any of these players will be ruled out for Sunday, although head coach Shane Steichen will announce on Friday if anyone has been ruled out to that point.

*The Ravens conducted a walk-through on Thursday. Thursday's practice report is only an estimation of a player's participation if there was a practice.*

Madubuike suffered a season-ending neck injury last September in Week 2, and Buchanan tore an ACL in December. Neither player is being ruled out for Sunday quite yet. Walker's injury is somewhat new, but his status is also uncertain.

The Colts and Ravens face off on Sunday at 1:00 p.m. ET at Lucas Oil Stadium on CBS.
