Washington Redskins Coach Mike Shanahan declined again Thursday to discuss details of the salary cap reduction imposed on the team by the NFL and the club’s failed challenge of that penalty.

“When it’s the appropriate time, I will comment on that,” Shanahan said following the Redskins’ practice. “Right now is not the appropriate time. When I’m able to do that, I will share all my thoughts with you. But right now is not that time.”

Shanahan previously had said he would elaborate on the details of the case after it was resolved.

An arbitrator dismissed the case brought by the Redskins and Dallas Cowboys contesting the salary cap cuts imposed on them in March, with the assent of the NFL Players Association. Stephen Burbank ruled last week that two teams could not challenge penalty because owners and the players’ union agreed to it, which amounted to a proper amendment of the league’s collective bargaining agreement.

The following day, the union filed a lawsuit in federal court in Minnesota accusing the league of collusion in 2010, when the NFL had no salary cap.

Both cases originate from the same set of circumstances during the uncapped year. The Redskins had their salary cap reduced by $36 million over two years and the Cowboys had their cap cut by $10 million over the same period because of the manner in which they structured players’ contracts in 2010.

Shanahan did not specify Thursday whether his ongoing refusal to comment on the salary cap case was the result of the collusion lawsuit.

“I can’t get into detail about it or else I would…. I’m not going to try to tell you something that I don’t mean. If you guys will just stick with me until I can actually talk about it, I’ll talk about it in detail. But right now, I can’t,” Shanahan said.

Shanahan previously has hinted that the salary cap reduction affected the Redskins’ offseason moves. He referred to the cap cut, without elaborating, in response to questions at the annual league meeting in March about the Redskins’ pursuit of free agent quarterback Peyton Manning and the team’s bid to re-sign linebacker London Fletcher.
