Day was sitting courtside when James dove for a loose ball with 3:07 remaining in Cleveland's 104-100 win over Oklahoma City. James saved the ball from going out-of-bounds, but crashed head-first into Ellie, who was sitting in the first row near the Thunder bench.
"It wasn't anything out of the usual besides the injury," James said. "But to me, obviously her health is very important and hopefully she's doing well. The guys told me she's doing great. So but you know, I was going for a loose ball. Just trying to keep a possession going and I hate that was the end result of it."
Day had a brace placed around her neck and head while remaining down for a few minutes and the game was halted. During the next stoppage, James checked on her and said after the game he had been informed she was doing OK.
Ellie was transported to Metro Hospital in Cleveland and held for overnight observation. She was accompanied in the ambulance by her husband.
Even with the scary collision, the incident did not alter James' view on courtside seats.
"I think it's a great experience for our fans," James said. "I mean that doesn't happen much. It's unfortunate it happened tonight but that doesn't happen much.
"Our fans are why our game is so great. Sitting courtside, it's all part of the game. It's pretty cool. If I was a fan, which I am a fan of the game but I would love to sit courtside and watch games."
