Terrell Owens, Ken Hamlin and Terry Glenn missed Tuesday morning's workouts on the first day of a three-day minicamp at Valley Ranch.
Owens is "tending to personal business" according to Cowboys public relations director Rich Dalrymple. Owen's status for the remainder of minicamp is unknown.
Glenn is not expected to attend any minicamp workouts. He didn't take a physical on Monday and remains at an impasse the Cowboys over an injury settlement.
Hamlin, the team's designated franchise player, is still seeking a long-term contract.
