ORCHARD PARK, N.Y. (AP) -- Buffalo Bills coach Doug Marrone said Monday he is planning to start third-string quarterback Jeff Tuel in the team's season opener against the New England Patriots on Sept. 8.
Tuel was signed an undrafted free agent out of Washington State.
Veteran Kevin Kolb is out indefinitely after sustaining a concussion against the Washington Redskins.
And while Marrone remains hopeful rookie EJ Manuel could be ready for Week 1 after hurting his left knee and undergoing what the team called "a minor procedure," the team will practice as if Tuel will be the starter.
On Sunday, the Bills signed quarterback Matt Leinart, an unemployed former first-round pick. Leinart, the 2004 Heisman Trophy winner at Southern California, was drafted by Arizona in the first round in 2006. After four seasons with the Cardinals, he spent 2011 with Houston and last year with Oakland.
Marrone also said cornerback Stephon Gilmore will miss six to eight weeks with a broken left wrist. He will not be placed on IR, because Marrone believes Gilmore could return "sooner than eight weeks."
There was some good news: The Bills welcomed safety Jairus Byrd back to practice for the first time since the two-time Pro Bowl player signed his one-year, $6.9 million franchise tender last week.
