From the Cleveland Plain Dealer...
Callaway's hearing is Thursday at 9:30 a.m. in Strongsville's Mayor's Court. The Browns are traveling to New York Wednesday to face the Giants in the preseason opener Thursday night.
Callaway, who was already in Stage 1 of the NFL's Substance Abuse Program, was on the practice field Monday and Tuesday, and scored a touchdown on a reverse in a goal-line drill on Tuesday, shortly after news of the citations broke.
"We are aware of the citation (and) are in the process of gathering more information and will comment further at the appropriate time,'' the Browns said in a statement shortly after ESPN Cleveland first reported the news.
Callaway was in Stage 1 by virtue of a dilute urine sample at the NFL Combine in March. A dilute sample is one in which there's too much water in the specimen, and counts as a positive test because sometimes players sometimes overload on water to mask drug use.
