Detroit Lions' Jack Campbell remains in hospital after suffering a neck injury but early indications are positive for his recovery.

He received medical assistance before being removed from the field, having been lying face down on the ground.

"Jack Campbell continues to rest and recover at a local hospital," a Lions statement said.

"Preliminary indications are positive and out of respect for Jack and his family we will not share any further information at this time."
