Rajon Rondo dismisses speculation on injury

Boston Celtics point guard Rajon Rondo has jokingly dismissed speculation over how he suffered a broken hand earlier this week.

The 28-year-old is expected to miss the first six weeks of the season at least after undergoing surgery on his left hand.

He insists that he sustained the injury after slipping in his shower at home, although the media have suggested it occurred during a visit to a trampoline park with his children.

"Am I under investigation?" Rondo joked during the Celtics' media day.

"Certain falls happen and you slip, and I slipped and tried to catch my hand. It wasn't like a banana [peel] slip. I actually almost caught myself. I landed on my knuckle on the windowsill in my home. That's what happened."

Celtics president of basketball operations Danny Ainge insisted that the franchise had no reason to doubt Rondo and will look forward to welcoming him back from the injury.
