Dallas Cowboys linebacker Rolando McClain's on-again, off-again career could be over this time.
McClain was suspended indefinitely Friday for violating the NFL's substance-abuse policy, his third suspension since the end of the 2014 season. That was his only full year with the Cowboys, although he missed three games with injuries, after reviving his career following a year away from the game.
The suspension likely means the end of McClain's Dallas career. The 27-year-old McClain was on his third straight one-year contract but never saw the field for the Cowboys. McClain was suspended the first 10 games this year after a four-game ban to start 2015.
