McClain is facing another suspension that could keep him out the rest of the year due to a missed drug test, a source informed told NFL Network Insider Ian Rapoport.
His previous 10-game suspension will end this upcoming Monday. Rapoport reported on Friday, however, that the Cowboys already were planning to keep McClain on the reserve/did not report list. In fact, the team doubts that McClain will come back to play in the NFL again following this latest step back.
The 27-year-old former first-round pick played the past two seasons in Dallas, following his first three campaigns in Oakland.
