The tumultuous career of trouble-prone former Ravens middle linebacker Rolando McClain took another rocky turn Thursday when he was suspended by the NFL for violating its substance-abuse policy.
McClain, entering his second year with the Dallas Cowboys, will miss four games after being signed to a one-year, incentive-laden $3 million contract this offseason.
"I apologize to my family, the Cowboys organization, my teammates and Cowboys fans for my mistake," McClain said in a statement issued through the NFL Players Association. "I will not break the rules of my profession in the future, and I regret my error."
McClain never played a down for the Ravens. He was signed in 2013, never practiced with the team and retired, then worked out for the Ravens in 2014 and was activated from the reserve-retired list before retiring again and being traded.
The Ravens received a sixth-round draft pick from Dallas in exchange for McClain and their seventh-round draft pick.
McClain revived his NFL career last year with the Cowboys last season despite missing four games because of injuries, including concussion, knee and hamstring problems. He had 108 tackles, second most on the Cowboys behind safety Barry Church, and also had a sack, a forced fumble and two interceptions.
McClain, a former Oakland Raiders first-round draft pick who won the Butkus Award as the nation's top linebacker at Alabama, was arrested for disorderly conduct and resisting arrest in his hometown of Decatur, Ala., during his first stint with the Ravens. That arrest was his third in a 16-month span.
McClain, 25, had arthroscopic surgery on his right knee this offseason and was absent for the majority of the offseason program before attending a mandatory minicamp in June.
