The Miami Dolphins have long been believed to be one of the most likely landing spots for Tua Tagovailoa, but the former Alabama quarterback has competition for the AFC East team's interest and No. 5 overall pick.

Miami doesn't view Tagovailoa as a "slam dunk" near the top of the draft, and its opinion of ex-Oregon quarterback Justin Herbert is "increasingly positive," sources told the Miami Herald's Armando Salguero.

The Dolphins are concerned about Tagovailoa's injury history and long-term durability, according to Salguero.

Tagovailoa is reportedly expected to make a full recovery from a fractured and dislocated hip he suffered in November. However, he also dealt with various other injuries during his college career, including multiple ankle ailments.
