Redskins,’ Cowboys’ penalties upheld

An NFL official says that an arbitrator has decided to let the league’s salary cap reductions against the Dallas Cowboys and Washington Redskins stand.

NFL executive vice president Jeffrey Pash said Tuesday at owners’ meetings in Atlanta that arbitrator Stephen Burbank ruled in the league’s favor in the salary cap dispute.

The NFC East rivals were penalized for overloading contracts in the 2010 uncapped season despite league warnings. The Redskins lost $36 million over two years and the Cowboys $10 million.
