NaVorro Bowman and the San Francisco 49ers have agreed upon a new contract.

Bowman's deal is worth as much $45.25 million with $25.5 million guaranteed.

Bowman and Patrick Willis comprise the best inside linebacker tandem in the NFL.

"NaVorro epitomizes what we look for in a 49er," 49ers general manager Trent Baalke said in a statement. "We are excited that the All Pro tandem of Willis and Bowman will be together in red and gold for years to come."
