Cowboys activate Kevin Kowalski

IRVING, Texas – The Cowboys have activated guard/center Kevin Kowalski off the physically unable to perform list and will have three weeks to activate him to the 53-man roster.

Kowalski had surgery during training camp for a severe case of tendinitis that kept him off the field for all of the organized team activities, minicamp and training camp.

He has been running for the better part of a month and said last week he does not feel any lingering issue from the tendinitis. The Cowboys will have a roster exemption for Kowalski to practice, but if they don't add him to the 53-man roster they would either have to cut him or leave him on PUP for the season.

“If he has a great week, in theory he could be active for this game this week,” coach Jason Garrett said Monday. “But we have three weeks to make that decision.”

Kowalski impressed many at Valley Ranch last season after making the team as an undrafted free agent. He played in 11 games last year at center and guard and the team hoped he could compete for the starting center spot in camp in the summer before undergoing surgery.

Phil Costa has missed the last two games because of a dislocated ankle suffered at Carolina on Oct. 21. He is no longer in a protective boot but he is still limping and is a ways away from returning to practice. With Ryan Cook as the starting center, the Cowboys have used guard David Arkin as the backup, but he has yet to see a snap this season.
