Free-agent RB Dominic Rhodes agreed to a two-year, incentive-laden contract with the Buffalo Bills on Friday, NFL.com’s Steve Wyche reports.

The addition comes in the wake of Bills starting RB Marshawn Lynch being suspended for the first three games of the 2009 regular season for violating the NFL’s personal-conduct policy. With Fred Jackson, who’s skipping voluntary workouts because he’s unhappy with his contract situation, and Xavier Omon among the other running backs on Buffalo’s roster, Rhodes will provide insurance.

Rhodes, an eight-year NFL veteran, has spent seven of his seasons in the league with the Colts. He started four games for Indianapolis last season and rushed for 538 yards and six touchdowns on 152 carries. Rhodes also caught 45 passes for 302 yards and three touchdowns.
