Dallas Cowboys defensive tackle David Irving has been suspended indefinitely for violating the NFL's Policy and Program for Substances of Abuse, NFL Network's Tom Pelissero reported Friday.
Irving went undrafted in 2015 but has suited up for Dallas the past four seasons. However, 2019 will be the third season in a row that Irving begins on the suspended list. The 25-year-old was suspended for the first four games of the 2018 season for violating the league's substance-abuse policy and the first four games of the 2017 season for a PED violation.
