Craig Allen Dingman (born March 12, 1974) is a former relief pitcher in Major League Baseball.

Dingman signed with the Detroit Tigers organization as a minor league free agent before the start of the 2004 season.

While playing catch with a teammate on February 4, 2006, however, his throwing hand spontaneously became pale and his arm lost all circulation from the elbow down.

The operation removed an artery from his right and transplanted it into the injured shoulder, re-routing blood around the damaged vessel.

[2] He returned to the Detroit Tigers in early 2007 for testing on his throwing arm but suffered a blood clot and fatigue in his shoulder.
