Suspended Tennessee basketball players Cameron Tatum and Melvin Goins passed drug tests administered shortly after their New Year's Day arrests and could be reinstated within the next two weeks, a source told CBSSports.com.

Tatum and Goins were two of the four Vols arrested Jan. 1 on gun and drug charges and were -- along with Tyler Smith and Brian Williams -- immediately suspended from the team. Smith subsequently took responsibility for the guns and was dismissed. The source said Williams has taken responsibility for the marijuana. Those developments are expected to lead to all charges against Tatum and Goins being dropped, and the players' negative drug tests have strengthened their case for a quick reinstatement, the source said.

Williams will serve a longer suspension. But he too will have a chance to be reinstated with stipulations, the source said. All three players must also go through a student judiciary committee. It's unclear when that will happen.

The Vols are 12-2 and ranked ninth in the Associated Press poll.

Their next game is Thursday against Auburn at Thompson-Boling Arena.
