CLEVELAND — Cleveland Cavaliers assistant Hank Egan had bypass surgery Saturday morning, and coach Mike Brown said there is no timetable for Egan's return to the team.

Brown said he has spoken with team doctors about the surgery, which was performed at Fairview Hospital in suburban Cleveland.

"He's going to be out for a while," Brown said. "The surgery went well."

Egan, 70, has been in coaching for nearly 40 years, including the last three as an assistant with the Cavs. Brown played his college ball at the University of San Diego, where Egan was the head coach in the early 1990s.

Egan also was the head coach at the Air Force Academy in the early 1970s. Among his players was San Antonio Spurs head coach Greg Popovich.

"He's old school," Brown said. "He's earned so much respect. When he has something to say, he comes straight at you. He doesn't beat around the bush."

Cavaliers forward LeBron James said Egan is in the team's thoughts.

"He's been around this game for a long time," James said. "If you ever need something or you need someone to talk to, you can go to him."

Egan also has been an assistant at San Antonio and Golden State in the NBA.
