Carolina Panthers wide receiver Kelvin Benjamin suffered no structural damage to his knee in their loss to the New Orleans Saints.
Benjamin was injured at the end of the first quarter, when his left leg was twisted under his body after a tackle. He left the game and did not return.
"He got an MRI last night, and it came back pretty good. We'll see how his treatment goes," Panthers head coach Ron Rivera said on Monday.
"They told me that it had all come out negative and there was nothing structurally wrong, which was good news because it was his repaired knee."
The diagnosis is a huge relief for Benjamin and the team, who tore his left ACL before the start of the 2015 season.
Rivera did not specify the extent of Benjamin's injury, or when he will return to the field. So far this season, Benjamin has 110 yards on nine receptions.
