Former Strikeforce champion Nate Marquardt is done with professional fighting.
The 56-fight veteran announced on his website Thursday that he is hanging up the gloves after 18 years of MMA competition. Marquardt, 38, made a name for himself as a top-ranked fighter during his time with the UFC, Strikeforce, and Japan’s Pancrase promotion.
In 25 Octagon appearances, Marquardt went 13-12 with notable wins over Jeremy Horn, Demian Maia, and Rousimar Palhares, among others. He failed to unseat middleweight king Anderson Silva in what would be his lone UFC title bout back in July 2007, but he would capture Strikeforce gold at welterweight five years later with a fourth-round knockout of current UFC champion Tyron Woodley.
