Auburn's wide receiver corps suffered another blow on Saturday, but the extent is not yet known.

Senior wide receiver Will Hastings, Auburn's starting "3" slot receiver, injured his knee during Auburn's first spring scrimmage at Jordan-Hare Stadium, a source confirmed. The extent of the injury it not yet known and Hastings will undergo further evaluation.

Hastings, who was in an orange non-contact jersey during the last practice before spring break returned to contact earlier this week and was also working as a kick returner.

Auburn's only other primary slot receiver on scholarship this spring is Griffin King.

Auburn Undercover first reported the injury to Hastings, who had 26 receptions for 525 yards and four touchdowns last season.

The injury to Hastings is the latest to Auburn's receiver corps, which lost Eli Stove to a torn right anterior cruciate ligament earlier this month. Starting flanker Ryan Davis returned to contact earlier this week following offseason shoulder surgery and starting "5" receiver Nate Craig-Myers was held out of contact for a practice earlier this month but has since returned.
