DeVante Parker is fine; Laremy Tunsil playing Thursday; Dion Jordan on NFI; Culliver headed to PUP

Easy day at Miami Dolphins camp. More importantly, good day at camp.

There is good news on the injury front in that DeVante Parker, Kenny Stills and Laremy Tunsil -- all of whom left practice Monday -- are generally fine. All three were at the walk-thru practice (really jog-thru) with all three participating.

And before you think it, severely injured players do not participate in any sort of practices. So all is well with these three.

Coach Adam Gase said Parker is day to day. He will not play Thursday in the preseason finale.

And next week day-to-day means he practices at least limited.

Tunsil continues to look more and more like the team's starting left guard. Nobody has declared it. Tunsil won't admit it. But among players it is a poorly kept secret. Laremy Tunsil is the Miami Dolphins starting left guard.

But just because he's the starter doesn't mean he thinks he's arrived.

He spoke today about needing to continue to improve. He spoke today about playing Thursday night in the preseason finale against the Tennessee Titans. (He's been told he is playing, he just doesn't know for how long).

“It’s up to the coaches," Tunsil said. "I just know I’m playing.”

Tunsil has not allowed a sack all preseason, although his run blocking needs to get better. So when a reporter asked if he'd experienced a breakthrough of sorts in making the switch from tackle to guard, Tunsil didn't exactly embrace the idea.

“I really don’t know what a breakthrough is," he said. "You can have a good game (or) a bad game. I really don’t listen to all the ‘breakthrough’ stuff. There’s room for improvement. I’m trying to get better every day and listen to the coaches."

The Dolphins have already reached the mandated 75 man roster limit. The way they did it is smart.

The team today placed DE Dion Jordan and linebacker Zach Vigil on the reserve-non-football injury list. So they no longer count on the roster going into the season.

This means Jordan and Vigil cannot play until after the sixth game of the season at the earliest. The Dolphins can or cannot choose to pay these players.

For Jordan, who is on a conditional reinstatement from the NFL after he sat out last year for testing positive in the substances of abuse program, this obviously means more time away from the field.

Consider how long it has been: The last time Jordan played was 2014. In his three-year career the former first round draft pick has started one game for the Dolphins. He was the first round pick of the 2013 draft.

Vigil, who came to the team as an undrafted rookie last year, has two career starts for the Dolphins.

Jordan thus becomes an insurance policy should the team feel uncomfortable with its defensive end talent midway through October. This roster move also allows him to rehabilitate fully from the knee injury and surgery that he apparently suffered while he was suspended.

Some folks have been wondering what the Dolphins are going to do with cornerback Chris Culliver, who is currently on the active-physically unable to perform list. As I've reported, the Dolphins expect to place Culliver on the reserve-PUP list when the cuts to 53 are made Saturday.

That means Culliver will not count toward that final roster number as he continues to rehabilitate from the knee injury and surgery he sustained in Washington last year but can come off the PUP during the season to help the Dolphins if they need it.
