UFC lightweight contender Anthony Pettis has decided to go under the knife to alleviate some nagging injuries and is currently looking at a return to action at some point this summer.
The news comes from Tuesday's episode of "UFC Tonight" and was subsequently confirmed with Pettis' manager, Mike Roberts, by MMA Weekly. Pettis is expected to be sidelined for about eight weeks.
The decision comes after the UFC changed course and decided to book a rematch between newly crowned lightweight champ Ben Henderson and former title holder Frankie Edgar after originally agreeing to grant Pettis a long-awaited shot at the belt.
Pettis recently scored a highlight-reel head kick KO of Joe Lauzon at UFC 144 in Japan last month, the same event in which Henderson won the title with a unanimous, but closely contested nod over Edgar.
