In his first public comments since undergoing surgery to repair a torn ACL in his right knee, Rajon Rondo said it is "frustrating" not to be playing with his Boston Celtics' teammates.

"I'm in a place now where I am OK with it," Rondo said. "I know this is my main focus, getting healthy."

Rondo suffered the injury on Jan. 25 against the Atlanta Hawks and didn't initially believe it was serious.

"I didn't hear a pop. ... I thought I could play through it," he said.
