Chip Hooper, 53, who had been battling cancer for four years, attended the Golden Grizzlies' senior day Feb. 26. It was the first time he was in attendance since Max Hooper transferred to Oakland from St. John's after his sophomore year.
According to the Detroit Free Press, Detroit Pistons owner Tom Gores helped arrange Chip Hooper's transportation from California to the game in Michigan. The elder Hooper watched his son while still strapped into a gurney.
Max Hooper said Friday the regular-season finale was an "indescribable moment" and something he and his family won't forget any time soon.
"This is a very sad day for the Oakland Basketball family," coach Greg Kampe said in a statement. "Max is traveling to California to spend a day with his family. We ask that you offer your prayers to his family."
Oakland earned the No. 2 seed in the Horizon League tournament and opens play Monday night against the winner of Sunday's game between Wright State and Detroit. Hooper's status for the game has yet to be determined, the school said.
