Bills DT Marcell Dareus to enter rehab facility

— -- ORCHARD PARK, N.Y. -- Buffalo Bills defensive tackle Marcell Dareus announced Saturday that he is entering a rehabilitation facility.

The NFL announced Tuesday that Dareus will be suspended for the first four games of the regular season for a violation of the league's substance-abuse policy. Dareus told reporters Wednesday that he missed a drug test.

"After careful consideration of recent events within my life, I have made the decision to enter a rehabilitation facility," Dareus said in a statement released Saturday by the team. "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."

"We are fully supportive of Marcell and this decision to take the time he needs to seek treatment," the Bills added in a separate statement.

News of Dareus entering the rehabilitation facility emerged minutes after he was seen leaving New Era Field in street clothes -- less than two hours before the Bills' preseason game Saturday against the New York Giants.

"He is with the team, but he will not be playing today," Bills general manager Doug Whaley said Saturday.

Whaley also had no time frame as to when Dareus would rejoin the team.

"There is no timetable," he said. "Everybody knows in these processes, you don't want to put a timetable on it."

The Bills had rebuked Dareus in a statement Tuesday, saying he "put himself first" and let down the team.

"I really don't have much to say," Dareus said Wednesday. "Words really doesn't mean anything now. It's all action. That's all I'm going to do. I'm going to come back and do the best I can. I just apologize to my team and my family. I embarrassed my kids and who I am and who I'm working to be."

The sixth-year defensive tackle was previously suspended for the first game of the 2015 season for a violation of the substance-abuse policy, stemming from his May 2014 arrest in Alabama for criminal possession of a controlled substance.

Dareus, 26, was named to the Pro Bowl in 2013 and 2014. The No. 3 pick of the 2011 draft, Dareus signed a six-year, $100 million extension with the Bills last September.
