The Detroit Lions have agreed to terms with year contracts.

Hill has been Detroit's backup quarterback for the past two seasons behind Matthew Stafford. He made 10 starts for the Lions in 2010 after Stafford received a season-ending injury and had a 3-7 record while throwing for 2,686 yards with 16 touchdowns and 12 interceptions.

Through 32 career games -- 26 starts -- with Minnesota, San Francisco and Detroit, Hill has accumulated 6,209 yards, 39 touchdowns and 23 interceptions.

Backus was selected by the Lions in the first round of the 2001 draft and he has spent his entire 11-year career with Detroit.

He has never missed a game in his career, but is currently rehabbing a torn right bicep which he suffered in the Lions' playoff loss to the New Orleans Saints.
