Cowboys cut Livings year after free-agent signing

IRVING, Texas (AP) — The Dallas Cowboys have released guard Nate Livings just a year after signing him as a free agent to

shore up their offensive line.

The Cowboys originally put Livings, who prepped at Washington-Marion before playing at LSU, on season-ending injured reserve after he had the second arthroscopic surgery on his right

knee in the past six months during training camp.

Dallas still has to pay Livings $1.7 million

this season. He signed a five-year contract with the Cowboys last year

and started

all 16 games in 2012. But Dallas had the worst per-game rushing

average in team history last season, and Tony Romo was sacked

a career-high 36 times for the second straight year.

The Cowboys also released defensive tackle Travis Chappelear.
