Check out the series of events below:
Walden was flagged 15 yards on the play for unnecessary roughness, but he wasn't ejected. It was the third consecutive play in which the Colts had committed a personal foul.
The penalties helped the Titans get a field goal on the drive to take a 17-3 lead late in the second quarter.
