Unable to stop himself, LeBron James launched his 250-pound body into the air, crashing hard into the lap of a courtside spectator unable to get out of his way.

He had no idea he'd just plowed over the wife of PGA champion Jason Day.

There was nothing anyone could do.

Scrambling for a loose ball, the Cavaliers star flattened Ellie Day, sending her to the hospital during the fourth quarter of Cleveland's 104-100 win over the Oklahoma City Thunder on Thursday night.

Day, who gave birth to her second child last month, was carried from Quicken Loans Arena on a backboard, placed on a stretcher with her head immobilized and taken to MetroHealth Medical Center. She was accompanied from the building by her husband, who moments before the collision had chipped foam basketballs to the crowd as part of a promotion.

As she was being treated by medical personnel inside the arena, James came over to check on her, grabbing her hand.

"She squeezed my hand and said she was fine," James said. "I think she was just a little weary. For me, obviously, her health is very important and hopefully she is doing well. The guys told me she's doing great now. For me, just going for a loose ball, I tried to keep the possession going, I just hate that that was the end result."
