St. Louis Cardinals legend Lou Brock has been diagnosed with bone cancer and is currently receiving treatment for multiple myeloma, the team announced Thursday.

Brock -- a 2-time World Series champ -- was a first ballot Hall of Famer in 1985 and currently serves as a special instructor coach for the Redbirds.

The 6-time All Star was scheduled to make a guest appearance at a team event later this month, but canceled due to the treatments.

"Jackie and I appreciate the prayers and support we have received from our many friends and fans in the Cardinals community," Brock says.

"We count ourselves blessed that I am receiving the best possible medical treatment and we look forward to seeing many more Cardinals World Series Championships in the future."
