The San Francisco 49ers announced on Thursday they have signed quarterback Thad Lewis to a one-year deal.
Lewis (6-2, 200) originally signed with the St. Louis Rams as an undrafted free agent on April 25, 2010. He spent the majority of his rookie season on the Rams practice squad, was later waived by the team on Sept. 3, 2011, and claimed off waivers by the Cleveland Browns the following day. After spending the 2011 and 2012 seasons with the Browns, Lewis was claimed off waivers by the Detroit Lions on May 28, 2013 and later traded to the Buffalo Bills on Aug. 25, 2013.
In 2013, he appeared in six games (five starts) for the Bills, throwing for 1,092 yards and four touchdowns and a passer rating of 81.0. Following his release from Buffalo, he spent time with the Houston Texans before re-signing with the Browns on March 12, 2015. He was released from the Browns on Sept. 5, 2015 and signed with the Philadelphia Eagles on Sept. 21, 2015 where he spent the remainder of the season.
A 28-year-old native of Hialeah, Fla., Lewis started four seasons at Duke University (2006-09) where he appeared in 47 games and set school records for career passing yards (10,065) and passing touchdowns (67).
