Pittsburgh Pirates right-hander Jameson Taillon underwent surgery for suspected testicular cancer at Allegheny General Hospital on Monday morning, the team announced.
Taillon, who was placed on the 10-day disabled list with a groin injury on Saturday, alerted the Pirates' medical staff of an abnormality. The 25-year-old consulted with Dr. John C. Lyne, who performed the surgery.
"Jameson has again proven to us what a strong person he is by the way in which he has reacted to this development. We are appreciative of Dr. Lyne and the staff at Allegheny General Hospital for their invaluable expertise and efforts in caring for Jameson," Pirates general manager Neal Huntington said.
"We have told Jameson that our only priority is his health and well-being. His teammates, our coaches, baseball staff and entire organization will support him in his recovery in every possible way and we will keep him in our thoughts and prayers."
The recommended treatment plan for Taillon is pending further testing.
Taillon (2-1) allowed six runs and eight hits in five innings against the Cincinnati Reds on Wednesday and was saddled with his first loss of the season.
Taillon has a 7-5 career mark with a 3.36 ERA in 24 games since being selected with the second overall pick of the 2010 draft.
