Cornerback Sidney Jones was carted off with an apparent left leg injury Saturday at Washington's pro day.
Jones sustained the injury on one of the final defensive back drills of the day.
As he was beginning to make a break out of his backpedal, Jones immediately began favoring his left leg and tumbled to the ground. Jones began to grab at the underside of his leg after coming to a stop.
There was no immediate update from the school regarding the nature or severity of Jones' injury.
"It's really tough, just because Sidney's one of our best friends, all of our best friends, (and) he's a great prospect coming out," Washington safety Budda Baker said.
"Felt like he could have been the first corner and still can be the first corner off the draft board. The last drill, last thing you've got to do, and that happens. Definitely sad, but we know Sidney's strong and he's going to still be there."
A two-time All-Pac-12 selection, the 6-foot, 186-pound Jones has been projected to be among the first cornerbacks selected in April's NFL draft.
In USA TODAY Sports' most recent mock draft, he was projected to be selected by the New Orleans Saints with the No. 11 overall pick.
