Hurst, the No. 25 overall pick in this year's draft, was the first tight end selected. The news of Hurst's injury, first reported by NFL Network, comes as a surprise, as he finished practice on Thursday.
With Hurst sidelined, the Ravens' top two ends are Nick Boyle and Maxx Williams, both of whom are known for their blocking. Rookie third-round pick Mark Andrews can impact the passing game, but he has battled a hamstring injury all summer.
This is the most significant injury of the offseason for the Ravens. Before Hurst's injury, every starter was expected to be healthy enough to start the regular season.
