Ernie Johnson skipping baseball playoffs due to blood clots

Veteran broadcaster Ernie Johnson announced Monday that he is skipping the baseball playoffs due to blood clots in both legs.

In a video message posted to Twitter, Johnson said doctors found the clots during a routine physical and advised him not to fly while taking blood-thinners.

"When you are doing the playoffs, there's a lot of flights in a compressed time, and blood clots are nothing to be messed with," Johnson said. "As tough as it is for me to miss baseball's postseason, it's the thing for me to do."

Johnson, 62, was scheduled to call the Houston Astros-Cleveland Indians series on TBS. The three-time Sports Emmy Award winner will be replaced by Don Orsillo, the voice of the San Diego Padres.
