Shane Carwin announced via Twitter that he would be returning to action in October at UFC 104. Sherdog.com has since confirmed that his likely opponent will be Cain Velasquez.

Though no contracts have been signed yet, Carwin has verbally agreed to the match according to a source close to the 11-0 heavyweight prospect.

Carwin recently returned to training after reconstructive surgery to repair a severely broken nose suffered in his knockout win over Gabriel Gonzaga in March of this year. Carwin showed himself to be a contender after escaping off his back and knocking Gonzaga, a former UFC title contender, unconscious with a vicious right hand.

Velasquez (6-0) is coming off a devastating three-round dismantling of Cheick Kongo last month. The highly touted prospect displayed a dominating ground arsenal in the win, but also showed he needs a little more polish in the stand-up game. Kongo dropped him to open the first and second rounds before Velasquez put him on his back and hammered away en route to the unanimous decision victory.

The winner of the bout would surely be in line for a shot at the UFC heavyweight crown, likely in early 2010.
