Lions cornerback Darius Slay, the second-round pick who isn't competing in this weekend's rookie mini-camp after arthroscopic knee surgery, spent the two-hour practice Saturday attached to the hip of defensive coordinator Gunther Cunningham.

"Basically you could say it was like a private tutor," Slay said. "He was teaching me a little something, teaching me a little about football and basically seeing where my head was at — mental reps."

Slay did some light running with the rest of the players during warm-ups, but he was reluctant to discuss his injury or when he might return. He didn't say whether he'd be ready for OTAs in two weeks.

"I am just going to continue to work hard like I've been doing and come back as fast as I can," he said.
