BROOKLYN, N.Y. – One-time UFC light heavyweight title challenger Glover Teixeira is switching up his style to make sure his final fighting years are successful.

When Teixeira (27-7 MMA, 10-5 UFC) thinks about retirement, the 39-year-old Brazilian doesn’t have a set date. But he doesn’t want to stick around too long.

“I want to keep fighting,” Teixeira, who on Saturday faces short-notice replacement Karl Roberson at UFC on ESPN+ 1, told MMAjunkie on Thursday at media day. “I want to prove it to myself. I feel great. I feel my conditioning is there, and I train with young guys.

“But, yeah, I don’t want to be fighting in old age and have bad fights.”

Teixeira’s UFC career has seesawed in recent years with wins over up-and-comers and bad losses to top contenders. But he still aims to fight several times this year.

When he decides to hang up his gloves, it will be his own decision. He doesn’t take any sort of lesson from watching his former training partner, UFC Hall of Famer Chuck Liddell, suffer a dramatic knockout loss in a comeback fight against Tito Ortiz this past November.

“It has nothing to do (with that),” Teixeira said. “Chuck does it because he loves to do it. He’s one of the best of all time, and he’s always going to be one of the best of all time.”

Teixeira said he’ll always be the aggressive fighter that throws heavy leather in the octagon. He’ll just be a little smarter as he moves forward.
