So how important is playing this preseason for the fifth-year safety?
"I think it's very important," Delmas said after practice Tuesday. "A warrior or any leader wants to get out there and fill out the team.
"Is it important for me to get out there? Yes. But is it wise? Right now I don't think so."
The Lions have had Delmas on a very specific practice plan geared toward getting him ready for the regular season.
"I'm definitely on schedule for the regular season, it's just trying to get into these preseason (games)," Delmas said. "I'm kind of doubtful about it, but I still want to get out there and participate with my team before the regular season."
Ideally, the Lions would want some preseason action for Delmas so he can knock some of the rust off and get into the playing groove a little bit.
But if last year's Eagles' game is any indicator, it doesn't seem to be a big deal if he doesn't.
There are a number of positives that can come out of the competition we're seeing along the offensive line. But maybe one that's not talked about all that often is how many reps different players are getting in training camp and how that could help down the line.
The offensive line has been relatively injury free the last couple years, but if there are injuries this season, the fact that so many players are getting reps because they're fighting for starting spots could be a real positive later on this season.
"I definitely think there's a benefit to that," head coach Jim Schwartz said. "It does help you in those situations because you do have guys that have gotten quality reps that the team has confidence in. I wouldn't underestimate that part of it either.
"When a player goes and he's able to perform well in a preseason game or in a tough practice, coaches have confidence in him. The front office has confidence in him. Just as much as that, the players have confidence and they know that he can get the job done if he has to go in."
The team signed cornerback Conroy Black and waived cornerback
Black spent most of last season on the Lions' practice squad. He was released in May. He's a big cornerback (6-0, 187) with great speed and knows the scheme.
The Lions play the Cleveland Browns on Thursday and will likely be without cornerback
It was easy to forget early in training camp that receiver Ryan Broyles was only eight months removed from ACL surgery. He was participating almost daily at practice, though not quite every rep.
Broyles' practice time has tapered off recently in a plan to thwart off any soreness (which he said he had last week) or setbacks. He sat out Tuesday's session.
"We're flexible with his schedule, but he's been going about two days on and one day off now," Schwartz said.
The team practiced without nine players, including receiver
