Patriots captain Jerod Mayo has led a series of voluntary player workouts in Massachusetts for his teammates, according to a source, ensuring the Pats won’t be as susceptible to injury when training camp eventually opens.

The workouts are completely permissible because they’re being run by players, and the Patriots’ staff has not been involved.

Safety Patrick Chung, quarterback Brian Hoyer and safety Bret Lockett have been among the players in attendance, although a few others have also been present, according to the source. It is believed that every Patriots player has been invited to attend the workouts.
