Louis Delmas was on the field but not participating during the first day of mandatory minicamp Tuesday, and he was in no mood to talk to the media about his injured knee.

"I don't know what to tell you, I've been hurt," he said, as reporters walked along with him as he left the field.

When asked how his injured knee felt, he said, "Great. It feels just like how it was last year."

That can't be encouraging. Delmas did not participate in OTAs or mini-camp last year. He was on the field for the first couple of days of training camp but then was shut down and eventually had another surgery.

But when pressed, Delmas shut the interview down.

"Can you leave me alone, seriously," he said.

Coach Jim Schwartz said Delmas will not participate in this three-day minicamp and it is still unknown whether he will be ready for the start of training camp at the end of July.

"Patience is a very difficult thing when you are a player," Schwartz said. "But for a player like Delmas, patience is the thing he has to have right now. He has to be patient enough to work through it and give it time to heal, then take it as it comes and not get ahead of schedule.

"Lou is working hard. He'll be back on the field sometime, but it won't be at this minicamp."

Delmas has had surgery on both knees the last two years. It was the left knee that was operated on before last season. Neither Delmas nor the team will confirm there has been any other surgical procedure since the operation before last season.

Delmas got back on the field for the final few weeks last season, but he wasn't completely healthy.

Schwartz was asked if the team can still count on Delmas for the start of the 2013 season.

"There is a long way to go before we worry about stuff like that," he said. "Now is not the time. Everybody wants to put starting jobs up for grabs and depth charts, but we're really not at that point right now.

"Let's get to training camp and see how it goes."
