(SportsNetwork.com) - The NFL Players Association has suspended and fined Elvis Dumervil's former agent for a paperwork snafu that led to the player's release by the Denver Broncos in March.

Marty Magid's certification as an NFLPA contract advisor was suspended for six months and he was fined $25,000, the NFLPA said Tuesday.

The union says Magid's "negligence" contributed to the events surrounding Dumervil's release.

The Broncos had been negotiating with the defensive end and his agent on a deal that reportedly would have reduced his salary from $12 million to $8 million for this season.

Dumervil rejected, then accepted the offer, according to the team. But after an NFL deadline to submit Dumervil's contract paperwork wasn't faxed in time, the Broncos released him.

Dumervil, 29, fired Magid and signed with the Baltimore Ravens after six years with the Broncos. He led the NFL with 17 sacks in 2009 and had 11 last season. He has 5 1/2 sacks and 19 tackles in seven games for Baltimore.

Magid can appeal the penalties leveled by the NFLPA's Committee on Agent Regulation and Discipline.

The NFLPA said its decision to discipline Magid doesn't mean it can't take action against the Broncos for conduct it says may have violated the league's collective bargaining agreement with the union and Dumervil's rights under the CBA.
