Under terms of the new deal, Black will make $3.65 million over the next three seasons and has a chance to make another $1.8 million in incentives, the source said. The signing is significant because it could indicate a release of one of Jacksonville's veteran tackles.
The Jaguars used their first two draft picks on tackles -- Eugene Monroe in the first round and Eben Britton in the second. They currently start veterans Tra Thomas at left tackle and Tony Pathos on the right side. Knowing that the Jaguars valued Black enough to sign him, it is very likely a veteran tackle could be moved.
The 29-year-old Black came to the Jaguars last season after stops in Kansas City and Houston. He has played in 56 games during his six year career, but did not play any games for Jacksonville last season.
