Fox’s Glazer Straddles Jobs as N.F.L. Reporter and Trainer

To football fans, Jay Glazer is the shaved-headed, goateed N.F.L. reporter for Fox Sports.
To some of the league’s players, he is their mixed martial arts trainer.
Earlier this month, Glazer’s worlds intersected vividly when one of his clients, Brian Cushing, a Houston Texans linebacker, tested positive for a banned substance and was suspended for four games.
