Santa Clara, Calif. ? Brian Jennings will be the San Francisco 49ers’ long snapper for longer than he ever imagined.

The 49ers signed Jennings to a five-year contract extension Saturday, locking up a flawless performer on their solid special teams units through 2014.

Jennings hasn’t made a glaring mistake on Sundays ever since the club drafted him in the seventh round nine years ago. He’s been recognized as one of the NFL’s most consistent long snappers since leaving Arizona State in 2000, even making the Pro Bowl after the 2004 season as a special selection by NFC coach Jim Mora.

“In a position like mine, longevity is one of your only accomplishments,” Jennings said. “I play a don’t-screw-it-up position. It feels good to be loved, to be wanted, to be appreciated for something I put so much time into.”
