"David Irving is dealing with off the field issues," Jones said. "By agreement and by design, he is not here... [Irving is] addressing his issues and they are ongoing ... but I don't expect to see him at camp."
Irving was suspended to start the first four games of the 2017 season for violating the NFL's policy on substances of abuse.
The 24-year-old skipped offseason organized team activities and reported to mandatory minicamp out of shape.
NFL Network's Jane Slater reported that Irving is now in shape but dealing with other off-field issues.
"It was reported this morning that he was in rehab, but when I reached out to people close to him it's actually been a situation where he has been in and out of rehab this summer," Slater said on Inside Training Camp Live. "It's not just a substance abuse issue he is dealing with, although he has been suspended four games to start the season because of that. His is a little bit more complicated. He is dealing with several issues. He's got a team in place that's trying to get him back to the facility. Get his mind right."
The 6-foot-7 pass rusher owns the physical talent to be a dominant force in the NFL, but first, he's got to get the rest of his life in order.
