Does Black extension signal end for Pashos or Thomas?

Posted by ESPN.com's Paul Kuharsky

The Jacksonville Jaguars are presumed set at tackle for the long term with first-round pick Eugene Monroe and second-rounder Eben Britton. They started at left and right tackle, respectively, in Thursday night’s preseason finale against Washington.

But earlier in the day the team made a move that may indicate more about its veterans, Tony Pashos and Tra Thomas. The Jaguars signed backup Jordan Black to a deal that runs for three years and is worth $3.65 million with an additional $1.8 million in possible incentives, according to ESPN.com senior write John Clayton.

So something is brewing and the team will be dealing or cutting a name lineman.

Pashos, who started at right guard Thursday night against Washington, or Thomas, the left tackle signed as a free agent this offseason, could be on the way out.

Uche Nwaneri and Maurice Williams are valuable because of their versatility. Nwaneri can play all three inside spots and Williams, who was listed as the starter at right guard before Pashos' shift, can play anywhere on the line if needed.

Pashos signed as a free agent in 2007, getting a five-year, $24 million contract. Thomas’ incentive-laden deal was for three years and from what I can find the financial details were never reported.

Brad Meester is the starting center and Vince Manuwai, the team's best run blocker, is back at left guard after suffering a season-ending knee injury in last year's opening game.
