Former Celtic Eric Williams, journeymen big men Kelvin Cato and Linton Johnson, and Esteban Batista, the first Uruguayan to ever play in the NBA, all worked out for the Celtics yesterday.
All are expected to continue their workouts today, with coach Doc Rivers and his staff expected to invite at least one and quite possibly two to training camp.
A team source stressed last night that none of these players have been offered guaranteed contracts, though Batista is reportedly demanding exactly that in exchange for a training camp invitation.
