Vaughn (ankle) sat out Monday's 102-78 preseason loss to the Pistons.

Vaughn has missed two games in a row due to the sprained left ankle, and it's uncertain if he'll be ready to go for the preseason finale Wednesday against the Pacers. The Bucks listed Vaughn as one of the starting wings when training camp began, but after shooting 2-for-13 from the field in his two preseason appearances before suffering the ankle injury, it now looks unlikely that he'll hold down a role on the top unit heading into the regular season.
