"I guess it's just something I am going to have to deal with," Delmas said.
Delmas started training camp on the PUP list and didn't start practicing until the end of the second week. He's taken part in just two padded practices and hasn't practiced yet on consecutive days.
"You saw him on Wednesday, he can run around at full speed, but he's not at the point where he can put those kind of days on top of each other right now," coach Jim Schwartz said.
Actually, Delmas said he has yet to even attempt to reach full speed.
"No, if I did I'd probably miss a week," he said, laughing. "I look forward to turning it loose for the first game (of the regular season)."
That can't be encouraging. Delmas has been battling this groin injury since June.
"I felt all right (last Thursday), but not as good as yesterday," Delmas said. "With groin injuries, the best healing process is to give it rest -- a couple of days on and a couple of days off. That's the best treatment. A groin injury is never going to heal if you keep aggravating it."
Schwartz is doggedly sticking to the plan, and to his belief that Delmas will be ready to go in the season opener.
"The good news is, when he goes he's able to go fast," he said. "He has fresh legs and obviously that's a part of it. But he's not limited when he practices. I would rather him do that and then take the next off rather than have him limping around at practice."
Schwartz identified Delmas as the top defender on the roster in February. He was a difference-maker as a rookie, but the Lions' roster is devoid of options if Delmas is out for a significant period of time or the injury lingers.
This has the look of an injury that's going to hover all season, which is at least partly why the Lions' brass is keeping a keen eye on the goings on in Kansas City with safety Jarrad Page.
Page, 25, remains unsigned and has asked the Chiefs to trade him. The Lions, who have had interest in Page in the past, certainly would be willing to talk should the Chiefs decide to grant his wish.
