Glover Teixeira and the Pursuit of Excellence

Sign up for ESPN+ and order UFC 275: Teixeira vs. Prochazka

Glover Teixeira hears the doubt. In fact, he has heard it for years.

The venerable Brazilian will defend his undisputed Ultimate Fighting Championship light heavyweight title against Jiri Prochazka in the UFC 275 main event on Saturday at Singapore Indoor Stadium in Kallang, Singapore. Teixeira, 42, unexpectedly rose to power when he submitted Jan Blachowicz with a rear-naked choke and seized control of the 205-pound weight class a little more than seven months ago.
