With less than three weeks remaining until the start of the 2020 NFL draft, the health of former Alabama quarterback Tua Tagovailoa continues to be the biggest story around the event.

Yet unlike the months of January, February and March -- which were filled with positive updates on Tagovailoa’s recovery from November hip surgery -- the beginning of April has seen some doubt creep back into the public conversation.

Earlier this week, Bleacher Report draft analyst Matt Miller noted that “multiple teams” rank former Oregon quarterback Justin Herbert above Tagovailoa. The same day, ESPN’s Adam Schefter questioned whether the Miami Dolphins -- a popular projected landing spot for Tagovailoa at No. 5 -- would actually pick him if he was on the board.

And on Thursday, former Dolphins and New York Jets general manager Mike Tannenbaum took it a step further by saying it would be “irresponsible” for a team to draft Tagovailoa in the top 10 picks because of a lack of certainty over his health.

Alabama coach Nick Saban, speaking to reporters Thursday for the first time since early February, weighed in.

“I’m not a doctor, and I can’t comment on where Tua is and what he’s doing, but we’ve tried to continue to do everything we can from a rehab standpoint,” Saban said. "I think his agents and his representation now are kind of determining what the factors are.

“I can’t really comment on where Tua is. We think his rehab has gone extremely well, we think he’s able to do things on a schedule relative to the way we all thought he would be able to do them and he’s very positive and upbeat with where he is right now. That’s really about all there is for me to say about that.”

Part of the problem Tannenbaum noted is that NFL restrictions resulting from the coronavirus outbreak have prevented teams from hosting Tagovailoa on pre-draft visits and evaluating him medically. His scheduled April 9 pro day was also canceled because of the virus.

Tagovailoa and his agents have attempted to quell any fears in recent weeks. A day after Tagovailoa posted videos to social media of him moving through passing drills, one of his representative told AL.com that his latest medical scans would be sent to all teams that requested them and there were no lingering medical concerns.

NFL Network reported Thursday that Tagovailoa underwent a combine medical recheck by an independent physician, with guidance from all teams, that was sent across the league.

“I certainly recommended that to our players that have rechecks coming up and send it to all of the teams,” Saban said Thursday. “That’s about all you can do right now.”

Tagovailoa also conducted interviews with ESPN and NFL Network on Wednesday, saying he is “100 percent” and would be able to play in a game right away.

Yet questions seem to persist about Tagovailoa, coincidentally or not during a time on the NFL calendar when teams attempt to obscure their draft plans and misdirect opponents.

On Thursday, the South Florida Sun Sentinel reported that decision-makers on the Dolphins are split on Tagovailoa.

“Some feel Tagovailoa is too much of a medical risk to take in the top five, much less trade up to acquire,” the outlet reported. “And according to a well-placed source, coach Brian Flores is apparently in this camp.”

The first round of the NFL draft is still scheduled to be held April 23, although selections will be made remotely by NFL teams with a planned public gathering in Las Vegas scrapped because of coronavirus concerns.
