Two University of Utah students including a fullback who played for the U. football team - have been ordered to stay in a federal halfway house.

Martel Black, 19, and Samuel Simmons, 18, were ordered to the community treatment center during an initial appearance Tuesday before U.S. Magistrate Ronald Boyce. Darren Hughes, another U. football player, also appeared before Boyce but was released after posting $500 of a $5,000 signature bond. Boyce insisted, however, that Hughes report daily, in person, to a pre-trial detention services officer.A nine-count federal criminal complaint against the three students charges them with conspiracy to distribute nearly 4 pounds of cocaine.

Black, a junior fullback from National City, Calif., was charged with five cocaine trafficking counts and a single count each of selling marijuana, conspiracy and illegal weapons possession. Hughes, a junior wide-receiver from Lynwood, Calif., and Simmons, from Glenwood Calif., are each charged with three counts of cocaine distribution and a single conspiracy charge. Simmons is also charged with a weapons violation.

Boyce appointed G. Fred Metos as Hughes' attorney and also agreed to appoint attorneys for Black and Simmons. All three requested that the court appoint them an attorney since none of them said they could afford their own.

Black and Simmons will be allowed to leave the community treatment center to attend school, but must reside in the facility.
