Northwestern sophomore running back Treyvon Green was immobilized for precautionary reasons and taken to the hospital in an ambulance after being hit in practice Friday.
Green suffered the unspecified injury when he absorbed a hit by sophomore safety Ibraheim Campbell during Friday's practice, which included full pads.
Green had movement in all limbs as he left the field, according to a team spokesperson.
Evanston Hospital public relations associate Kelli Spencer said he was treated and released from the facility.
Northwestern coach Pat Fitzgerald, who departed with Green to the hospital, said in a statement all tests results were negative and that a full recovery was expected.
"I would like to thank our entire athletic training staff for their quick response and care in this situation," he said. "The safety and welfare of our student-athletes, for which we are responsible on a daily basis, is our top priority at all times."
Green has been considered to be in the mix for Northwestern's starting running back this season. His 362 regular-season rushing yards last season were the most by a true freshman since Tyrell Sutton in 2005. Green also rushed for four touchdowns last season.
