Former Nebraska offensive lineman Richie Incognito is being held by police on involuntary psychiatric hold after an altercation at a Miami gym, TMZ reported Wednesday.

According to the report, the longtime NFL guard threw a dumbbell at another gym patron early Wednesday morning.

"Law enforcement tells us Incognito was placed on an involuntary psychiatric hold to be evaluated," the report says, noting that the hold is different than being placed under arrest.

Also from the report: "We spoke with the alleged victim who tells us Incognito first threw a tennis ball at him for no reason -- before grabbing a dumbbell and heaving that as well.

"The alleged victim says Incognito was rambling about the government and screaming at the man to 'get off my (expletive) playground.'"

Incognito had announced his retirement from the Buffalo Bills earlier in the offseason, but the franchise released him off of their reserved/retired list last week after he said he wanted to make another run at playing.

Incognito was an All-Big 12 pick in 2003 but was kicked off the team by new head coach Bill Callahan in the fall of 2004.
