ORCHARD PARK, N.Y. (AP) — Free-agent quarterback Matt Leinart signed with the Buffalo Bills on Sunday.
Terms of the deal weren't disclosed.
Leinart fills an immediate need at Buffalo's injury-depleted quarterback position. The Bills later added quarterback Thaddeus Lewis in a trade that sent linebacker Chris White to Detroit. Undrafted rookie Jeff Tuel also is on the roster.
Kevin Kolb left the Bills' game Saturday against Washington because of concussion-like symptoms and first-round pick EJ Manuel is out for the rest of the preseason with a left knee injury.
Leinart, the 2004 Heisman Trophy 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.
Lewis spent the last two seasons with Cleveland. He started the Browns' 2012 regular-season finale against Pittsburgh, completing 22 of 32 passes for 204 yards with a touchdown and an interception.
