(UPI) -- Free agent Hamza Abdullah, a safety who has played for the Broncos, Browns and Cardinals, has not been in the NFL since 2011.
He showed how upset he was at the NFL on Thursday when he unleashed a string of expletives at the league on Twitter.
He said that the league denies that football causes brain damage and ragged on the NFL combine, which he said "strips us of our manhood."
"[Expletive] you @NFL #NFL," Abdullah began.
"[Expletive] you NFL for lying to these people and denying the fact that football causes brain damage," Abdullah tweeted.
Though he admitted players "knew the risks" and "would do it again," Abdullah said players often try to hide injuries because "the contracts aren't guaranteed."
He then claimed that some of his injuries were covered up, saying "[Expletive] you NFL for misdiagnosing all our [expletive] injuries."
He also criticized the league for its treatment of former players.
"[Expletive] you NFL for doing your former players the way you're doing em."
"We just thought/assumed we would be taken care of after it was done," he tweeted.
Referring to the suicides of several former football players, he said, "How many former players have to kill themselves before you guys [expletive] realize, that they're pushing us to it."
"It's not poor choices by the player, it's the [expletive] NFL loading the gun, and us pulling the trigger."
After that, he offered his suggestions.
The NFL said they have tried to reach out to Abdullah through its Player Engagement Staff.
We are "reaching out to him to see if we can be of assistance," a representative said.
Abdullah commented on his rant on Friday, and apologized for his language -- kind of.
