Falcon Big Man Has Another Surgery: Air Force center Nick Welch underwent yet another surgery yesterday, this time on his left ankle. Welch, who underwent surgery on a broken bone in his left foot two months ago, had a tendon repaired in his ailing ankle. Welch started all 30 games last season, finishing second on the team in scoring with 12 points and averaged 3.6 rebounds per contest. It is expected that Welch will be back in January for the start of the Mountain West Conference slate against BYU Jan. 5. [9/9/05]
