The Bengals signed free agent RB Kenny Watson on Tuesday.

Watson (6-0, 220; Penn State) is a seventh-year NFL player. He played for the Bengals from 2003 through Game 4 of this season. He had been released this past Saturday, Oct. 4.

Watson was Cincinnati’s leading rusher last season with career-highs of 763 rushing yards and 1137 yards from scrimmage. In Games 1-4 this season, he had 32 rushing yards on seven carries (4.6 avg.) and two receptions for three yards.

The Bengals also announced that they have signed rookie CB Simeon Castille to the practice squad.

Castille (6-0, 195; Alabama) originally signed with the Bengals as a college free agent on May 2. He was the only college free agent to make the season-opening roster, and he played in the Bengals’ first four games, making six tackles. He was waived from the roster this past Friday.
