Question: Who is a former professional American football quarterback who broke his left hand and had a professional American football halfback replace him however he was relieved by Tittle in the fourth quarter of the game?  
Context: The 1963 Rose Bowl was a college football bowl game played on January 1, 1963, at the end of the 1962 college football season.  It was the 49th Rose Bowl Game.  The USC Trojans defeated the Wisconsin Badgers, 42–37.  This is the first #1 versus #2 match-up to occur in a bowl game, although #1 versus #2 match-ups had occurred previously as regular season games (typically referred to as "Games of the Century").  Ron Vander Kelen, the Wisconsin quarterback and Pete Beathard, the USC quarterback, were both named the Rose Bowl Player of the Game.  Down 42–14 in the fourth quarter, Vander Kelen put together a number of drives to score 23 unanswered points and put the Badgers in position to win the game.  Due to the historic #1 versus #2 bowl match-up, the number of Rose Bowl records set, and the furious fourth quarter rally by Wisconsin, this game frequently appears on lists of "greatest bowl games of all time."

He was in every play both on offense and defense and seemed impervious to injury.  On several occasions he was thrown hard, with several others on top of him.  But he always came up smiling.
