Foster (26-3, 12 KOs) is now The Ring, IBF, WBC and WBO titleholder after dropping Navarrete (40-3-1, 33 KOs) twice and beating him by unanimous decision in San Antonio.

The lone remaining title for Foster to claim for undisputed champion status is held by Anthony Cacace, who defends his WBA crown against Nick Ball on December 19.

"My dream is to become undisputed. I need one more to become undisputed and fulfill my dream, and then I'll go see Shakur Stevenson," Foster said during his post-fight press conference.

Foster has a boatload of bouts to consider in 2027 and beyond.

Chief among them is Vasiliy Lomachenko, who was sitting ringside at Frost Bank Center to announce an eventual challenge. Lomachenko, who turns 39 in February, plans to come back after retiring last year with hopes of being a 130-pound undisputed champion.

"I want Loma to get a tune-up fight or something. When I beat him, I don't want any excuses," Foster said. "I think Loma is a great champion. That's a big fight and a great skill-for-skill fight … If it presents itself in the future, I love it."

Also waiting in the wings for Foster is certainly his least-desired option in WBO mandatory challenger Charly Suarez.

Foster, 33, may also consider a wild-card clash against Rafael Espinoza. The longtime WBO featherweight champion, like Foster, is promoted by Top Rank, and would have to move up to 130 pounds.

Once Foster moves up to 135, fights against uncrowned kings Shakur Stevenson and Gervonta Davis would be monster matchups, while encounters against lightweight crownholders Floyd Schofield (WBO), William Zepeda (WBC) and Abdullah Mason (WBO) would give him a shot at becoming a two-division champion.

"I got about one or two more fights left in me at 130. I can push it to go undisputed, and after that I am going up," Foster said. "I'm taking challenge after challenge."
