Celtics coach Doc Rivers underwent a biopsy Sunday morning to determine if lesions found on his throat were cancerous.

The test results came back negative and Rivers joked about the scare on Tuesday.

"I'm going to be around for a little while, it looks like," Rivers said. "I'm sure that disappoints everyone."

Rivers revealed that at the urging of former Celtics coach Jim O'Brien he's undergone annual examinations of his throat and vocal chords for the past three years because of the stress placed on those areas by his profession.

"Jim O'Brien suggested it two or three years ago and said every coach should do it," said Rivers. "I'm glad I did it.

"I think most coaches should because we yell and use our throat a lot. It makes you more susceptible."
