Manchester United striker Wayne Rooney has apologized to 9-year-old Jamie Thomas, who suffered a broken wrist when a stray shot by Rooney during warmups flew into the stands.

"I want to apologize to Jamie Thomas," Rooney wrote on Twitter. "I have arranged for a letter and a signed shirt to be sent to his home address."

Jamie's father, Andy, said the injury happened when his son tried to block Rooney's shot in the warmup before United's game with Wolves on Sunday.

"It shook him up a bit but he's fine about it now and I don't think it's put him off going to other games," Andy Thomas said. "I don't think Rooney realized what he had done, otherwise I am sure he would have come over."
