Dan Henderson will return to action on Dec. 4 against Renato “Babalu” Sobral according to a report on MMA Junkie.

A long-rumored matchup between Dan Henderson (25-8 MMA, 0-1 SF) and Renato “Babalu” Sobral (36-8 MMA, 2-1 SF) will headline a currently unannounced Strikeforce event slated for Dec. 4 at the Scottrade Center in St. Louis.

The fight is set for the light-heavyweight division and will air live on Showtime, according to multiple sources close to the event, who told MMAjunkie.com (www.mmajunkie.com) that the promotion formally will announce the event early next week.

Herschel Walker is expected to compete in his second pro fight in the co-main event. His opponent is TBD at the moment.

A heavyweight match-up between Fedor Emelianenko and Antonio Silva was once rumored for the Dec. 4 card, but now appears to be “unlikely.” There’s still a possibility of it happening in January.

Also of note, depending on what time the event is set at, it could very well go head-to-head with the TUF 12 Finale on Spike TV.
