The University of Colorado has implemented a new voluntary drug-testing program for athletes that replaces the one ruled unconstitutional in August by a Boulder, Colo., district judge.

Athletic Director Bill Marolt said the university still plans to appeal Bellipanni’s ruling, which struck down a stricter drug policy that required mandatory random testing.
