NFLPA executive director DeMaurice Smith will review the exchange of contract documents that led to Elvis Dumervil's release from the Denver Broncos on Friday, according to The Denver Post. Dumervil was released within an hour of agreeing to restructure his 2013 salary from $12 million to $8 million.

The paperwork of Dumervil's restructured contract was not filed by the 4 p.m. ET deadline. Denver asked the league office if it would honor the verbal agreement on the revised contract but the request was denied, according to The Post. The newspaper reported that Smith will look into the matter because Dumervil may have been hurt most by the botched contract exchange.

Had the Broncos not released Dumervil before Friday's deadline, his $12 million salary for 2013 would have become guaranteed. According to a source, both Dumervil's reps and the Broncos reached an agreement at 3:25 p.m. ET on the restructured contract. But the team did not get a fax from Dumervil's agent until 4:06 p.m. ET, so the Broncos had to release him, according to the source.
