Dallas Cowboys All-Pro linebacker Micah Parsons was on the field for Tuesday’s organized team activities at Frisco, Texas.Parsons had been a no-show at voluntary workouts, forcing the Cowboys to address the situation last week. Parsons sought permission from team brass to work out on his own in Austin, Texas.”We’re comfortable with that. That’s not unlike a lot of guys,” vice president Stephen Jones said last week.Parsons has been working to put on weight, preparing for what he said was a transition to a base defensive end role.”It’s hard battling 300-pound guys at 255 pounds every week,” Parsons said at the end of last season.
