Nate Davis set to sign deal with Seattle Seahawks

Quarterback Nate Davis, who demonstrated his strong throwing arm during the past two 49ers exhibition seasons, will sign a future contract with the Seattle Seahawks, pending a physical, two league sources said Tuesday.

Davis, a fifth-round draft pick from Ball State in 2009, never stepped on the field in a regular-season game for the 49ers. In two exhibition seasons, he completed 52 of 93 passes (55.9 percent) for 615 yards with three touchdowns and three interceptions.

Former 49ers general manager Scot McCloughan, who selected Davis in the draft, is senior personnel executive with the Seahawks, champions of the NFC West.

The 49ers released Davis before the 2010 season opener to sign veteran Troy Smith, whom the Baltimore Ravens cut two days earlier. Davis spent the entire season on the 49ers’ practice squad.

Coach Mike Singletary criticized Davis in August for failing to put in enough extra work during the offseason to learn the 49ers’ system.
