The good news for boxing fans is that an attractive welterweight matchup between Keith Thurman and Shawn Porter will happen at some point.

The rub is that "some point" is no longer December 12. 

Sources have informed that the planned showdown will move from current rumored plans to a yet-to-be-determined date and location. The likely scenario is for the fight to land at MGM Grand in Las Vegas during the first quarter of 2016. 

The fight is by no means canceled, but at the same time fans and media alike should not expect for it to headline on December 12 at AT&T Center in San Antonio. NBC was to televise the bout in primetime as part of its

Premier Boxing Champions

(PBC) series once it was ready to be formally announced - which was due to take place this week. 

However, the decision has been made to reevalute and determine the best course of action for the mouthwatering clash. 

PBC representatitves declined comment when asked for additional details or to confirm the bout's current status. 

Once the final working date is determined, Thurman (26-0, 22KOs) will make the sixth defense of his version of the welterweight title he claimed in July '13. A 10th round knockout win over Diego Chaves saw his status soar from rising contender to one of the top fighters in boxing's deepest division. 

The unbeaten boxer from Clearwater, Florida has emerged as a showcase attraction for the PBC movement. His 12-round win over Robert Guerrero headlined the first-ever PBC telecast, which aired March 7 in primetime on NBC and remains the most watched televised bout of 2015 to date. 

Four months later, Thurman enjoyed a homecoming fight in Tampa, with his knockout win over Luis Collazo in July launching the PBC on ESPN series. 

Porter (26-1-1, 16KOs) has also enjoyed a breakout year on free TV and regional cable. The former welterweight titlst - who turns 28 on Tuesday - rebounded from his title fight loss to Kell Brook last August with two wins on the year. He was forced to settle for late replacement Erick Bone in the opening bout of the first PBC on Spike TV telecast in March, scoring a 5th round knockout. 

Three months later came his biggest win to date, outpointing Adrien Broner over 12 rounds in their agreed upon catchweight bout in June. The non-title fight was billed as the "Battle of Ohio" with Broner from Cincinnati and Porter having been born and raised in Akron, but wound up airing live on NBC from Porter's adopted hometown in Las Vegas. 

With the aforementioned bout moving from the December 12 date, the planned show at AT&T Center now takes on a new look. 

Local promoter Leija-Battah Promotions had a hold on the venue, which will now host a pair of heavyweight fights, as reported Monday evening by senior writer David Greisman. Amir Mansour will square off versus Artur Szpilka, while Chris Arreola faces Travis Kauffman.
