SUSSEX, Virginia (CNN) -- Suspended NFL quarterback Michael Vick must adhere to tightened restrictions after he tested positive for marijuana use, a federal judge said Wednesday. Suspended Atlanta Falcons quarterback Michael Vick tested positive for marijuana in a September 13 drug test. Vick tested positive for the drug on September 13, a court document from the Eastern District of Virginia shows. As a result, U.S. District Judge Henry E. Hudson ordered Vick to "submit to any method of testing required by the pretrial services officer or the supervising officer for determining whether the defendant is using a prohibited substance." Those methods could include random drug testing, a remote alcohol testing system "and/or any form of prohibited substance screening or testing," the order said.
