Ryan Tannehill continues to look impressive.

DAVIE — The reviews on quarterback Ryan Tannehill for this week’s three-day organized team activities that started Tuesday are positive and steady, with the latest coming from right guard Jesse Davis and safety T.J. McDonald.

Tannehill, who is recovering from left knee issues that caused him to miss the last 20 games, has been getting favorable comments from coaches and teammates since starting the offseason program in April, and that hasn’t changed now that he’s on the field for OTAs.

“He looks good,” McDonald said of Tannehill. “He looks real good right now. His leadership is also great on and off the field.”

McDonald said such a steadying voice is good for a team.

“His leadership is what I think we missed the most,” he said.

As for Tannehill’s interaction with Davis, who became a starter late last season, it’s been limited but Davis has noticed Tannehill is always around the facility.

“Just locker room stuff, on the field, him being in the building,” Davis said. “He’s a helluva worker. I didn’t think I’ve ever not seen him in the building somewhere when I’ve been in here. He’s always doing something — rehabbing, getting extra, coming up to us with something like, ‘Hey, we’re going to try this today,’ or ‘We might try that.’ It’s awesome what he does.

“He’s been a great leader, gets us all together, get us on the same page. I think it’s going to be awesome to work with him.”

McDonald at safety

Dolphins safety T.J. McDonald knows one thing about the 2018 season — he’s not playing linebacker. That message, despite media and fan speculation, was delivered by coach Adam Gase earlier this month, and it was confirmed and reinforced by McDonald on Tuesday.

“I’m a physical player,” McDonald said, “but like I said, I’m a safety.”

McDonald started last season alongside fellow strong safety Reshad Jones. The experiment didn’t work as well as Miami hoped, according to Gase. That’s part of the reason the Dolphins drafted Alabama safety Minkah Fitzpatrick in the first round (the other part of the reason the Dolphins drafted Fitzpatrick is because he unexpectedly fell to them).

But the rumors about Fitzpatrick becoming a safety or a hybrid safety/ linebacker persisted during the offseason.

“I hear all that,” McDonald said about changing positions. “I’ve been a safety this whole time been in the league. So that’s all speculation. I didn’t hear any of that from the coaches.”

Team waives Hickey

The team waived offensive tackle Sean Hickey. Losing Hickey, who spent the 2017 season on the practice squad and was undrafted out of Syracuse in 2015, thins out some of the competition for offensive line depth.

Hickey, who spent time on the practice squads for New Orleans (2015), New England (2015), Minnesota (2016) and the New York Jets (2016), was never able to gain footing as a top backup with Miami.

The Dolphins primarily use offensive tackle Sam Young as the backup but also have Eric Smith, Zach Sterup and Jesse Davis, currently playing right guard, among the options for backup offensive tackles.

The team also acquired offensive tackles Joseph Roubbens and David Steinmetz during the offseason. Miami still starts right tackle Ja’Wuan James and left tackle Laremy Tunsil.
