The Cowboys were not done with their moves at 5 p.m. when they reduced their roster to 53. They now are at 52 after placing offensive guard Nate Livings on injured reserve.
Livings underwent arthroscopic surgery on his right knee on Aug. 2 and has not practiced since. It is his third career surgery on that knee, the second since last season.
The Cowboys signed Livings to a five-year, $18.7 million contract last season with $6.2 million guaranteed. His $1.7 million salary for 2013 was guaranteed this season even if he wasn't on the team.
Livings started all 16 games last season. He had two penalties, including one hold, and allowed five sacks, according to STATS, prompting the Cowboys to seek a replacement.
They already had penciled Ron Leary into the starting lineup at Livings' left guard spot before Livings' injury. Leary is rehabbing from arthroscopic knee surgery, but Cowboys owner Jerry Jones said Thursday he expects Leary to be ready for the opener.
