Georgia confirmed the two were arrested on misdemeanor possession of marijuana. Each was released on $1,000 bond Wednesday morning, according to the Athens-Clarke County jail report.
Patrick, a linebacker, has 13 tackles in seven games. He was the top backup to starting middle linebacker Jake Ganus.
Rivers, a defensive end, has one tackle in two games.
Coach Mark Richt said in a statement Patrick and Rivers ''made a very poor decision and I'm extremely disappointed.''
Richt said he hopes the two ''have learned a valuable life lesson that will benefit them moving forward.''
