Dallas Cowboys cornerback Mike Jenkins was not cleared by renowned orthopedic surgeon James Andrews to practice, ESPN Dallas’ Calvin Watkins reported Monday night.

Jenkins underwent shoulder surgery after the 2011 season and has not practiced since. Originally, Cowboys head coach Jason Garrett said that Jenkins would probably be able to practice by the end of the preseason. But now that is unclear. From Watkins’ report:

Jenkins will continue his rehab work and conditioning until he is cleared. The Cowboys wanted Dr. Andrews to clear Jenkins first because he performed the surgery on the cornerback. If Jenkins had been approved by Dr. Andrews, Jenkins was then going to be seen by the Cowboys’ doctors to see if he could be cleared to practice.

At the start of training camp, coach Jason Garrett said Jenkins could return to practice by the end of the preseason. But now it’s uncertain when Jenkins will return.

Jenkins played in 12 games with the Cowboys last season, making 24 tackles and picking off one pass. The Cowboys dangled the disgruntled Jenkins as trade bait this offseason, with the Indianapolis Colts the most serious potential suitor.

Dallas became deeper at the cornerback position in the offseason, drafting Morris Claiborne with the sixth overall pick in the 2012 NFL Draft and signing free-agent cornerback Brandon Carr to five-year contract in March.

The Indianapolis Colts are in play to trade for Dallas Cowboys cornerback Mike Jenkins, a source confirmed to NFL.com’s Ian Rapaport. 

Jenkins is in the final year of his contract and has not participated in any of the Cowboys’ offseason activities. Cowboys head coach Jason Garrett said yesterday that the team is not going to trade Jenkins.

“If anyone understands, I understand, but at the same time, you want a guy like that to be around the team and what not,” linebacker Anthony Spencer said. “But it’s always a decision. I support him. He’s my teammate. Whatever decision he makes.”

Jenkins became expendable when Dallas drafted Morris Claiborne with the sixth overall pick in the 2012 NFL draft and signed free-agent cornerback Brandon Carr to five-year contract in March. That deal is said be around $7 million per season.

Jenkins had 24 tackles and one interception in 12 starts last season.
