Krzysztof Soszynski announced his official retirement from MMA Friday night during an interview on “Inside MMA.”

Soszynski went 26-12-1 in his MMA career and 6-3 in the UFC, but has not fought since a 2011 loss to Igor Pokrajac. He holds wins over the likes of Stephen Bonnar and Brian Stann, but cited memory loss and concern over future issues with his brain as the reason for retiring.
