LOS ANGELES • Ellie Day, wife of world No. 2 golfer Jason Day, was battered and bruised but spent Friday defending her husband and LeBron James as she recovers from a collision with the National Basketball Association great.

She suffered concussion symptoms as well as bumps and bruises after James crashed into her while diving for a loose ball during the Cleveland Cavaliers' win over the visiting Oklahoma City Thunder on Thursday.

She was stretchered off from her courtside seat and admitted to hospital before she was released on Friday.

"I am okay!! I am incredibly sore and exhausted," Ellie tweeted on Friday. "To the crazies that think Jason should have protected me - if he had had time to react, so would have I. LeBron is huge and had such momentum he could not have stopped!!"
