Alycia Baumgardner is open to fighting Katie Taylor if she can stun Mikaela Mayer in London this weekend.
The WBC and IBO super-featherweight title holder faces Mayer, who holds the WBO and IBF belts, in a unification bout ahead of Claressa Shields v Savannah Marshall, who clash for the undisputed middleweight championship on Saturday night.
Baumgardner comes into the fight as the underdog in the betting, but she is confident of pulling off an upset as she targets her third win on English soil in ten months after victories over Terri Harper and Edith Soledad Matthysse.
