This 1982 Maryland Terrapins game issue Aloha Bowl jersey was issued to #50, Greg Thompson. It does not appear to have been used in the game, as Thompson does not register on the stat sheet, and the jersey does not show any game use. It is possible, however, that Thompson was issued a jersey to wear on the sideline over his street clothes due to injury, or just not being active on the roster at that time.
This is a high quality Champion mesh jersey with heavy rubber lettering and numbers. The sleeves, tagging, and Aloha Bowl patch seem consistent to the jerseys worn by the Terps in that game.
