Report: Cowboys' Irving suspended 4 games for violating substance abuse policy

Dallas Cowboys defensive lineman David Irving will be suspended four games for violating the NFL's substance abuse policy, a source told NFL Network's Ian Rapoport.

Irving recorded 22 tackles, seven sacks, and a forced fumble in 12 games during the 2017 season.

This is the second suspension of Irving's career after he served a four-game ban for violating the NFL's performance-enhancing drugs policy in 2017.

A versatile lineman capable of playing both end and tackle, Irving's absence is a major setback for the Cowboys' defense.
