Karlos Williams Suspended: Latest Details, Comments, Reaction on Bills RB

The Buffalo Bills will be lacking depth in the backfield when the regular season starts, as running back Karlos Williams has been suspended for four games. 

Per NFL Network's Ian Rapoport, Williams' punishment is for a violation of the league's substance abuse policy. 

The Bills issued a statement regarding Williams' suspension Friday (via ESPN.com's Mike Rodak):

"

As an organization, we are disappointed that Karlos has put himself in this situation. Poor decisions such as this affect not only the individual, but the entire Bills organization. We will continue to work with Karlos through the various player programs we provide to assist him in making better decisions moving forward.

Williams was a terrific backup for LeSean McCoy last season. The former Florida State star averaged 5.6 yards per tote on 93 carries and led the team with seven rushing touchdowns. 

However, things were not going well for Williams even before he got suspended. The Buffalo News noted he showed up to Bills camp 20-25 pounds overweight, which led head coach Rex Ryan to state the team would have to set a "realistic weight-loss goal" heading into training camp later this month. 

The good news for Buffalo is that McCoy won't face any punishment from the NFL for a February nightclub brawl in which he was allegedly involved, per NFL Network's Mike Garafolo, who cited a league source. 

Even though McCoy went through some growing pains in his first season with the Bills, he still led the team with 203 carries and 895 rushing yards. He's the lead runner for the team, even though Williams made a strong impression as a rookie. 

In addition to McCoy's presence, quarterback Tyrod Taylor proved to be a terrific dual-threat player with 568 rushing yards and four rushing touchdowns. 

Ryan's offense is based on a power running game. Taylor was a breakout star at quarterback last season, but he benefited from the team leading the NFL in rushing yards. 

Losing Williams for 25 percent of the season is a huge blow for the Bills, but it won't ruin their chances of making a run to the playoffs so long as McCoy and Taylor stay healthy.
