The Kermit Washington incident
Despite Tomjanovich's noteworthy career as a player, he is perhaps best remembered for an infamous occurrence at the height of his playing career. In a December 9, 1977, game, the Los Angeles Lakers' Kermit Washington threw a punch during an on-court melee that struck Tomjanovich. The blow shattered Tomjanovich's jaw and face and inflicted life-threatening head injuries, leaving him sidelined for five months. He eventually made a full recovery, but his playing career slowly came to a halt and he was forced to retire in his mid 30s. The story and aftermath are recounted in the John Feinstein book The Punch: One Night, Two Lives, and the Fight That Changed Basketball Forever.
