From the article:
He was diagnosed with a high-ankle sprain during the Oct. 21 game against Washington and never played again despite remaining on the roster. Irving was not a regular participant in his rehab, Moore reports.
Still, the Cowboys paid Irving $2.9 million in 2018 as a restricted free agent. He becomes an unrestricted free agent next month.
Irving, 25, has served suspensions in back-to-back seasons. He opened the 2018 season with a four-game suspension for violation of the NFL’s substance abuse policy after violating the PED policy in 2017.
He also missed all of the offseason program and training camp dealing with off the field issues, including a custody battle for his daughter.
He is/was a helluva player, but the guy just can't seem to get out of his own way (beginning with - but not limited to - a stop sign).
