Sammy Watkins is continuing to work his way back from offseason hip surgery.

Watkins lines up for routes during OTAs with the Buffalo Bills, but he hasn't been running them.

"Mentally, I've got to get my reps," Watkins said Wednesday, via The Buffalo News. "I'm behind. I'm not there every day with the guys running routes. So, mentally, I've got to watch the defense, the coverages, watch how things move because I'm going to be coming back soon. And everything's got to be fast and I've got to pick it up."

Watkins is expected to be back in time for training camp.
