The junior was stretching out to catch a pass when he was hit by Rutgers safety Zaire Kitchen. Beaumont was bent back awkwardly and lay motionless on the field for several minutes.
He was able to wave to the crowd after being placed on the stretcher.
Louisville spokesman Rocco Gasparro said X-rays on Beaumont's neck were negative. He left the stadium in a neck brace while sitting in a wheelchair as a precaution.
Kitchen was penalized for unnecessary roughness.
