Heavyweight champion  Tom Aspinall puts his title on the line for the first time since being elevated from interim titleholder to undisputed champion in the UFC 321 main event on Saturday. The 32 year-old Brit takes on former interim titleholder Ciryl Gane in his first fight in 15 months. After winning the interim championship at UFC 295 and defending it at UFC 304, Aspinall was sidelined waiting for then-champion Jon Jones to accept a title unification bout
