Tim Jennings getting the day off (rested) was the only addition to the Colts injury report for Thursday. Robert Mathis returned to practice after Wednesday off (rested). The 3 players actually injured, Sanders, Federkiel and Roy Hall sat out again.
That means counting the PUP players the Colts have 19 of their 22 starters practicing and 57 guys have practiced on both days this week. The Colts appear to be the healthiest they've been all season.
