Marcell Dareus entering rehab after four-game substance-abuse suspension

Last week the NFL announced Bills star defensive tackle Marcell Dareus was suspended four games for a violation of the league's substance-abuse policy.

On Saturday, the team released a statement from Dareus indicating he would be checking into rehab for treatment of those substance-abuse issues.

"After careful consideration of recent events within my life, I have made the decision to enter a rehabilitation facility," Dareus said. "I feel this is the best decision for me, my family and my teammates as I move forward with my career. I appreciate the support of my teammates and the Bills organization through this process."

The Bills also released a statement, supporting Dareus.

"We are fully supportive of Marcell and this decision to take the time he needs to seek treatment," the team said.

Of all the issues for the Bills defense this offseason -- and there have been plenty of them, with both Reggie Ragland and Shaq Lawson battling injuries -- the Dareus suspension is the biggest issue. He's the key to Rex Ryan's unit up front and fully capable of disrupting offensive lines.

Now he's out a minimum of four games, and the decision to enter treatment has to bring additional games into question. It's impossible to try and figure out how long being in treatment will last (although 28 days is probably a good start), but a month from now the Bills will have played two games with a matchup against the Cardinals looming.

Dareus is eligible to return October 9 against the Rams.

Saturday was a busy day for Buffalo too, with the team announcing the release of running back Karlos Williams. It's been a rough preseason for Rex and Co., who just a few months ago won the offseason.
