George Mason forward Johnny Williams will miss Thursday's game against Drexel with a concussion, a team spokesman said.
Williams suffered the concussion in Sunday's 71-51 loss at Northeastern. Forward Jonathan Arledge is expected to start in his place.
Williams is the Patriots' second-leading scorer, averaging 7.0 points and 4.1 rebounds while starting all 20 games. Arledge is averaging 5.2 points and 3.9 rebounds for Mason (12-8, 5-3 Colonial) while appearing in every game and starting four.
With Williams out of the lineup, Mason will use its sixth different starting lineup of the season and its fourth in the last six games.
