Denver Broncos defensive end Elvis Dumervil was arrested in Miami on Saturday night.
According to multiple media reports, Dumervil is accused of aggravated assault with a firearm. The Denver Post reported the charge is a third-degree felony punishable by up to five years in prison. The Post said Dumervil was released from jail Saturday after he posted $7,500 bond.
The reports did not specify the circumstances surround his arrest.
"No charges have been filed. No aggravated assault or assault took place. And it is likely that once the full investigation is complete, no charges will be filed against Mr. Dumervil," Harvey Steinberg, Dumervil's attorney, told ESPN NFL Insider Adam Schefter.
The Broncos said they were aware of Dumervil's arrest.
"This is a very serious allegation, and we will thoroughly review the details while the legal process runs its course," the team said in a statement.
Dumervil, a Miami native, had 9½ sacks in 14 games last season after sitting out 2010 due to a torn pectoral muscle. The former fourth-round pick led the NFL with 17 sacks in 2009.
The Broncos drafted Dumervil out of Louisville with the 126th overall pick in 2006.
