Immediately after signing with the Tiger-Cats, Amerson played in the Labour Day Classic against Toronto, catching a touchdown pass and returning a punt for 24 yards. While the Tiger-Cats initially expected to use Amerson more in the rushing game than they had in the past, the team returned to using him as a receiving back by the end of September due to weaknesses in the offensive line. As the season progressed, Troy Davis emerged as the Tiger-Cats' starting running back and leading rusher while Amerson was used as a receiving back. After missing a game in early October due to bruised ribs, Amerson was effective as a receiver for the rest of the month, finishing with three touchdowns in the last two games of October. Due to a coaching decision to rest Davis prior to the playoffs, Amerson started in the final game of the regular season against the BC Lions.
