The Detroit Lions' second-round draft pick, Oklahoma wide receiver Ryan Broyles, could start his NFL career on the physically unable to perform list.
Broyles tore his anterior cruciate ligament during a game against Texas A&M late last season.
Broyles was able to run a 4.57-second 40-yard dash for scouts in April, just five months after having surgery to repair his anterior cruciate ligament, but he told the Detroit Free Press he couldn't give them a full timetable for his recovery.
"This guy is very talented. He's the leading receiver, most productive receiver really, in college football history," Mayhew said. "We think the world of Ryan and he fits with our offense. As soon as he gets healthy, he'll be in the mix. We were very excited to have him in the second round."
Broyles caught an NCAA Football Bowl Subdivision-record 349 passes for 45 touchdowns and 4,586 yards as a Sooner.
