Cribbs was given a one-game suspension and still faces a possible one-year jail term, the Akron Beacon Journal reported Wednesday.
The 6-foot-5, 195-pound Cribbs was arrested in January after police found eight bags of marijuana in his apartment. He was reinstated after agreeing Tuesday to plead guilty to fifth-degree felony drug possession, the newspaper said.
"This has obviously been a very difficult time for Josh, his wife Maria and their family," Coach Doug Martin said. "We're very happy to see this come to a close for them, and look forward to them putting this behind them. Our football team looks forward to putting this behind them."
Cribbs threw for 2,424 yards and 14 touchdowns and ran for 701 yards and 14 touchdowns last season as a junior. He will miss the season opener Sept. 4 at Iowa.
