Former Strikeforce women’s bantamweight champion Sarah Kaufman is now an Invicta FC title holder, as well. Kaufman scored an impressive submission win over a previously undefeated Katharina Lehner (7-1) in the main event of Friday’s Invicta FC 29 event, which streamed live on UFC Fight Pass from Scottish Rite Temple in Kansas City, Mo. The two fighters wasted little time in exchanging at the start of the fight, moving quickly to the pocket and trading punches in close range. Kaufman’s strikes reddened her opponent’s face almost immediately, but Lehner refused to back down, driving forward and moving inside while continuing to trade.
