IMG bolstered its management team following the news that Chairman and CEO Ted Forstmann is being treated for brain cancer.

The firm yesterday promoted Mike Dolan to president and chief operating officer, according to an internal memo obtained by The Post.

Dolan was executive vice president and chief financial officer at the global sports and media powerhouse, which reps golfer Tiger Woods and a host of top fashion models.

“Ted continues in his position as chairman and chief executive officer and will be working closely with Mike to continue his long-term strategy of growing IMG’s business,” according to the memo, which was confirmed by an IMG spokesman.
