Blackhawks team physician Michael Terry said Sharp was experiencing some abnormal abdominal discomfort Monday. He said the surgery was successful.
The Blackhawks open training camp this weekend.
Sharp led the Blackhawks with 34 goals last season and signed a five-year contract extension last month. He had a career-high 71 points and added three goals and two assists in the playoffs when the Blackhawks lost in the first round to Vancouver, a year after winning the Stanley Cup.
It's cool when you think about how many great American players have played the game and the two players that were at that 18-game point streak and what they've done in their careers. It's pretty cool right now, but it was kind of overshadowed by the loss.
