Rob Gronkowski caught passes from Tom Brady during a private workout on the campus of UCLA on Monday.
Brady’s personal trainer and business partner, Alex Guerrero, also attended the session.
Gronkowski retired from the NFL in March.
Gronkowski said on the Rich Eisen Show last week that “there’s definitely going to be times when you miss it and everything. . . . I mean I can’t really say how I’m going to feel about it when the games start rolling around and everything.”
