The Buffalo Bills experienced a shortage at running back due to injury last summer in training camp. On Friday the club learned they'll be short a ball carrier due to a league-imposed suspension come the regular season.
Running back Karlos Williams was served with a four-game suspension for violation of the league's substance abuse policy by the NFL.
In addition to notifying the Bills of Williams' suspension the league also informed the club that Williams will be eligible to return to the Bills' active roster on Monday Oct. 3rd following the team's Oct. 2nd game against the New England Patriots.
Williams is eligible to participate in all offseason and preseason practices and games, so he will be able to participate fully at Bills training camp.
Williams tied for the team lead last season in touchdowns with nine.
