Bullard (undisclosed) exited Sunday's practice early and was talking with trainers, Matt Schneidman of The Athletic reports.
It is unclear what type of issue caused Bullard to leave the field. Kitan Oladapo took over as the slot cornerback for the first team when Bullard left and will presumably fill the role if the starter must miss time. Rookie second-round pick Brandon Cisse may also get a shot at the slot cornerback or third safety role if Bullard must take a prolonged absence.
