Long time Yankees bench coach Don Zimmer has been hospitalized in Tampa with apparent kidney problems. According to a statement from his son, Zimmer has started dialysis treatment and is expected to be released on Thursday.

The 81 year-old baseball lifer was a staple of the Yankees bench during their dynasty run of the late ‘90s, serving as a coach for the club from ’96-’03. Zimmer is notorious for his roll in a infamous 2003 brawl between the Yanks and the Red Sox where he was taken to the ground by Pedro Martinez after he appeared to attack the pitcher. Zimmer currently serves as a senior advisor for the Tampa Bay Rays.
