Australian Olympic swimmer Mack Horton is praising a fan who encouraged him to have a mole on his chest checked out.

Horton, 20, posted a photo on Instagram on Thursday showing his bandaged chest after getting the mole removed.

“Shout out to the person that emailed the swim team doctor and told me to get my mole checked out,” he wrote along with the photo. “Good call. Very good call.”

Horton competed in the 1500m Freestyle, 400m Freestyle and the 4 x 200m Freestyle Relay in the Summer Olympics in Rio, and took home the gold in the Men’s 400m Freestyle Final.
