KANSAS CITY, Mo. — Canadian Sarah Kaufman submitted Katharina Lehner in the third round Friday night to win the vacant Invicta FC bantamweight title at Invicta FC 29.

The 32-year-old from Victoria forced the 28-year-old German to tap at 4:30 of the third via a rear naked choke at the Scottish Rite Temple. Kaufman (20-4) had come close to finishing it in the second round with an arm triangle but Lehner (7-1-0) survived, wagging her finger at the Canadian veteran as she regained her feet.

It marked the first submission victory for the 133-pound Kaufman, a former Strikeforce world champion.

The fight was contested on the feet until Kaufman secured double underhooks to engineer a takedown in the second round. She got another takedown in the third, opening up a cut over Lehner's eyes with some ground and pound before locking in the choke.

Kaufman, a UFC veteran, walked out to Michael Jackson's "Beat It" with friend and Olympic bobsled champion Kaillie Humphries in her corner.

The Canadian joins Brazil's Cris Cyborg as the only fighter to have won Strikeforce and Invicta titles.

Invicta Fighting Championships is a women's MMA circuit.
