Adams threw a series of punches during a punt late in the first half vs. the Titans.
Colts reserve linebacker Matthew Adams was ejected from Sunday's game vs. the Titans just before halftime for throwing punches during a punt.
Adams, 24, is primarily used on special teams and entered Sunday's contest with just one tackle on the season.
It is likely that Adams will face either a fine or a suspension following the punches.
Adams's ejection also marks the second time this year that a Colts player was ejected during a matchup with the Titans. The last time these two teams played, defensive end Al-Quadin Muhammad was ejected for hitting an offensive lineman.
The Titans led the Colts 35-14 at halftime.
