Despite a brief exchange with BJ Penn over Twitter for a fight last month, Jake Shields is not expected to meet the Hawaiian when he returns to the Octagon following his unsuccessful attempt to take Georges St. Pierre’s title at UFC 129. Instead, Shields is expected to take on Jake Ellenberger this fall, possibly at UFC 138 (tentative) on Nov. 19 in San Jose, according to MMA Fighting.

Though the fight has not yet been made official by the UFC, sources close to the bout confirmed to MMA Fighting last week that the fighters have agreed to the planned matchup for this fall.

While a location for the fight is not yet certain, one possibility is the UFC’s planned Nov. 19 card in San Jose, Calif. That will be the promotion’s debut in the northern California city, about 40 miles south of the San Francisco Bay area, where Shields lives and trains. That event is likely to be UFC 138, though it has not yet been made official by the UFC.

It won’t be an easy fight for Shields. Ellenberger is currently riding a four-fight win streak and his strong wrestling base and knockout power matches up well with Shields stylistically. This is definitely his chance to make a name for himself in the UFC welterweight division.

Update: Jake Shields won’t meet Jake Ellenberger at UFC 138, but they will fight. The UFC announced today that the welterweight match-up will headline UFC Fight Night 25 “Battle on the Bayou” instead. The fight won’t be a five-rounder though like Dana White recently stated all main events would starting after UFC 133. The announcement noted that the fight is only scheduled for three rounds. No reason was given.

The main event for UFC Fight Night in New Orleans on September 17 has been verbally agreed to as Jake Shields takes on Jake “The Juggernaut” Ellenberger.

“Ellenberger is on a mission to get his first shot at a world title, and Shields is determined to get another crack at it,” said UFC President Dana White. The televised bout is scheduled for three rounds.
