(AP) -- Running back Jerious Norwood has agreed to terms on a one-year contract with the St. Louis Rams, who need a backup for Steven Jackson.

The 28-year-old Norwood is on the sideline Tuesday night as the Rams practice in 102-degree heat.

Norwood spent almost all of last season on injured reserve with the Atlanta Falcons after injuring his right knee on a kickoff return.

Norwood missed six games in 2009 when he had a career-low 252 yards rushing in 10 games, including four starts.

He had a career high 633 yards rushing as a rookie in 2006 and 613 in 2007.

Jackson made his third Pro Bowl last year, rushing for 1,241 yards for third-best in the NFC.

He's the franchise's career leading rushing leader with 7,948 yards.
