JACKSONVILLE – The first day of 2015 rookie minicamp hardly was ideal.

Dante Fowler Jr., the Jaguars' first-round selection and the No. 3 overall selection in the 2015 NFL Draft last week, sustained what appeared to be an injury to his left knee midway through his first NFL minicamp practice on Friday afternoon.

Fowler went down holding his left knee during a team drill midway through the practice at the Florida Blue Health and Wellness practice fields. Fowler was rushing the passer at the time, and did not appear to make significant contact with an offensive player.

"(Jaguars Head Athletic Trainer Scott Trulock) just talked to me right now," Jaguars Head Coach Gus Bradley said after practice about an hour after Fowler left the field. "He's being evaluated right now. We'll know more tonight.

"I didn't really see what happened on the field. It happened kind of off to my side, but we'll find out more tonight."

Fowler, who worked in practice at the team's Leo pass rusher positon – the position the team expects him to play in Bradley's defense – left the field with the help of trainers. He did not appear to be putting significant weight on the leg.

Trainers attended to Fowler before he was taken inside EverBank Field – which is adjacent to the team's practice fields – on a cart.

"Sometimes injuries happen in the game," Bradley said. "It's just hard for me to speculate. Any time a guy gets injured it's not a pleasant thing. It's not a good thing whatever the injury is. It can set him back a couple of days, a week, or whatever. Whatever it is we'll deal with it and keep going."

Fowler played collegiately at the University of Florida. He was widely considered one of the three best prospects in the draft along with defensive end/tackle Leonard Williams of Southern California (New York Jets) and wide receiver Amari Cooper of Alabama (Oakland Raiders).
