Mississippi State cornerback Darius Slay, regarded as a potential first-round pick, tore the meniscus in his knee this offseason, raising medical questions with teams, league sources said.
Some doctors have told Slay he can play through the injury without undergoing surgery and other doctors believe surgery would be preferable, sources said.
Teams are aware of the injury and have wanted to see Slay's condition. Slay worked out Friday for the Atlanta Falcons and was said to look "great."
Slay was impressive at the scouting combine in February, sporting a time of 4.36 in the 40-yard dash. He also had 14 reps of the 225-pound bench press, registered a 35.5-inch vertical and claimed 124 inches in the broad jump.
