Jonathan Martin had a gun in his possession when he was detained by police, according to a report.

TMZ Sports says police believe Martin had recently purchased two weapons, including one that matched with the gun seen in his Instagram post. When he was found on Friday, he had a gun in his car.

TMZ Sports also says that Martin is undergoing a psychiatric evaluation.

Martin made a threatening post on his Instagram story last week that showed a photo of a gun with several bullets around it. The post specifically called out a few of Martin’s former NFL teammates, as well as his high school.
