Cowboys head coach Jason Garrett announced Irving was back at team facilities and is expected to practice, per Clarence Hill Jr. of the Fort Worth Star-Telegram.
Irving has yet to play this season after serving a four-game suspension for violating the NFL's substance abuse policy. He remained away from the Cowboys last week due to an ongoing custody battle over his five-year-old daughter.
Irving had a career year in 2017 despite playing just eight games. His season started with a four-game suspension due to violating the league's performance-enhancing drug policy. He was also sidelined for the final four games after suffering a concussion in Week 13 against Washington.
He recorded a career-high seven sacks in eight games. The 25-year-old finished second on the team in sacks, even though he missed half of the season.
The Cowboys are off to a 2-3 start in five games without Irving in 2018. Their defense hasn't been a problem, allowing the fifth fewest points per game in the NFL (19.2) and tied for sixth with 15 sacks.
It's unclear at this point when Irving will be ready to play, but Dallas will happily add another playmaker as the team tries to take a step forward in the NFC East.
