Tuesday through Thursday the Detroit Lions will hold a mandatory minicamp. Here are five things to watch for as they gather at Allen Park:

1. Safety Louis Delmas did not participate in OTAs the last three weeks because he is rehabbing his knee in south Florida. He’s in touch with the coaches and staff. OTAs were voluntary but this minicamp is mandatory. Seems like maybe we’ll see Delmas even if he’s just standing on the sidelines. Seems like the Lions would not have re-signed him if they didn’t think he could be on the field and, as is their way, they haven’t given any Delmas updates.

2. The right guard position will be one of the most contested throughout training camp and the preseason. Bill Nagy, who the Lions signed last season after he was released by the Cowboys due to an injured ankle, was thought to be a front-runner but he is still coming back from that injury. Rookie Larry Warford might not be ready to step in as a starter. That could be why two veteran guards — Jake Scott and Leroy Harris — were signed last week. We’ll see how Scott fits in this week. Harris is coming off knee surgery and isn’t ready to practice yet. Dylan Gandy has also been getting reps at the position which was left vacant when Stephen Peterman was not brought back.

3. Patrick Edwards has had a good offseason so far. Now he needs to keep it up. It’s time for other wide receivers to also get noticed. One thing for sure, Nate Burleson is up and running — it doesn’t appear he’s had any ill effects coming back from a broken leg.

4. Mikel Leshoure has not been 100 percent during the OTAs while dealing with a lingering hamstring injury. There’s real competition at running back this season, especially with the addition of Reggie Bush, so Leshoure needs to get back on the practice field. Last week he seemed certain he’d be fine for the start of training camp in late July, but not so sure about this week’s minicamp.

5. Not sure we’ll know who will be returning punts and kicks until we get a good look in preseason games, but still have to keep an eye on who they’re looking at during minicamp. It could be a way onto the 53-man roster for a guy like Steven MIller.
