Despite being one of the best college quarterbacks in the nation at the University of Alabama, Tua Tagovailoa's injury concerns appear to have him slipping on multiple NFL teams' draft boards.

Per The Athletic's Bob McGinn, three teams have taken Tagovailoa off their board entirely due to concerns from scouts and executives about his ability to stay healthy.

Rumblings about Tagovailoa's durability keep getting louder the closer we get to the 2020 NFL draft.

One AFC personnel man told McGinn that Tagovailoa was "a great college player" but added there are "three, four or five red flags staring us all in the face" that make it hard to risk a high pick on him.

B/R's Matt Miller wrote Friday that the former Alabama star could "absolutely fall in this draft because of injury concerns."

In the same article, Miller noted there is "growing buzz" that the Miami Dolphins will take Oregon quarterback Justin Herbert instead of Tagovailoa with the No. 5 overall pick.

Chris Cabott, Tagovailoa's agent, told Yahoo Sports' Eric Edholm that his client has been "fully cleared and ready to compete without any restrictions" following November surgery on his dislocated hip.

Tagovailoa also had two surgeries in the past two seasons to repair high ankle sprains. He suffered a broken index finger during Alabama's spring practice in March 2018.

When Tagovailoa has been able to play, he's been terrific. The Hawaii native threw for 2,840 yards, 33 touchdowns and three interceptions in nine games last season for the Crimson Tide.
