Rolando McClain's career with the Dallas Cowboys may more over than it already is.

According to Bleacher Report's Jason Cole, the former starting inside linebacker is abusing a codeine-based drug called "purple drank" — a combination of Sprite and codeine. Cole cites that victims sipping on purple drank, a.k.a. lean, often gain a lot weight. Cole also reports that McClain gained approximately 40 pounds this offseason.

"According to one source, he said it's almost impossible to ever see Rolando McClain playing for the Dallas Cowboys again," Cole reported.

In April, the Cowboys were reportedly seriously concerned with McClain's weight gain. McClain was spotted in the team's pump-up video for Orlando Scandrick and the cornerback's journey back to the football field. You can see the image of McClain looking a little overweight in the photo embedded below:

In 2014, McClain struggled with the Ravens workout program failing his first conditioning test of that offseason. McClain was coming off his brief retirement from football at the time. McClain entered last season a little heavier than his listed 255-pound playing weight. The linebacker was exhausted when he first took to the practice field before his first game of 2015 season after serving a four-game suspension. McClain also had knee surgery last offseason.

Training Camp is HERE, don't miss any Dallas Cowboys breaking news!

McClain is now preparing to serve a 10-game suspension for violating the NFL's substance abuse policy. He skipped out on OTAs as the Cowboys said he was at home dealing with family problems. McClain showed up to mandatory minicamp, but didn't workout with the team. Training camp started this past weekend and McClain was absent from the team charter.

If the Cowboys don't get him help, it might be a long time before he even sees another NFL playing field again.
