In a game against the Pittsburgh Steelers on January 3, 2010, Pat White suffered a helmet to helmet collision with Ike Taylor that left him unconscious and he was carried off the field, but released from the hospital the next day. After White was waived by the Dolphins (2010), he signed a minor league contract with the Kansas City Royals on September 10, 2010. On January 25, 2011, White was signed by the Miami Marlins to a minor league contract. White went on to become a member of the Edmonton Eskimos (Canadian football club), where he still plays.
