TUESDAY, 3:18pm: According to Brian McIntyre (via Twitter), Sanborn’s new three-year contract includes a $550K signing bonus, a slight bump up from the $530K bonus he got on his last deal. That’s the only guaranteed money on the extension.

FRIDAY, 5:51pm: Sanborn’s new deal is worth $3.3MM, or $1.1MM annually, according to Buscaglia (via Twitter). That’s a slight bump up from Sanborn’s last contract, and makes the Bills long snapper one of the league’s top five highest-paid players at his position.

5:31pm: The Bills have reached an agreement on a three-year contract extension for long snapper Garrison Sanborn, a source tells Joe Buscaglia of WGR 550 (Twitter link). The new deal ensures that Sanborn, whose contract was set to expire at season’s end, is locked up through the 2017 season.

Sanborn, 29, has been the Bills’ long snapper since joining the club in 2009. His most recent contract, a three-year pact, included a $530K signing bonus and annual workout bonuses of $25K, in addition to base salaries that exceeded the minimum. Assuming the Bills are still happy with his performance, we can probably expect similar numbers this time around, though terms have yet to be reported.

Sanborn’s extension is the latest roster move for a Bills team that also announced 10 cuts and placed three players on injured reserve earlier today.
