Bills backup QB Anderson retires

Backup quarterback Derek Anderson, who signed with the Buffalo Bills last October, has decided to retire from the NFL, the team announced Thursday.

“Derek let me know a few weeks back that he wasn’t sure if he could be committed (for the season) and wanted to still think about it,” Bills general manager Brandon Beane said in a statement. “So I knew going into the draft that this was something that could potentially happen. But it wasn’t definite. We talked this week and he let me know today that he is going to retire.”

Anderson, 36, a sixth-round pick of the Baltimore Ravens in 2005 who began his NFL career with the Cleveland Browns in 2006, appeared in 78 career games, completing 909 of 1,674 passes for 10,878 yards with 60 touchdowns and 64 interceptions.

He led the Browns to a 10-5 record in 2007 — making the Pro Bowl for the only time in his career — then after two more seasons with the Browns, played for the Arizona Cardinals (2010) and Carolina Panthers (2011-17) before joining the Bills.

Last season, he played in only two games with Buffalo (both starts) and completed 42 of 70 passes for 465 yards with no touchdowns and four interceptions.

Among the remaining Bills quarterbacks are starter Josh Allen and backups Matt Barkley and Tyree Jackson, an undrafted free agent.
