LeBron James' Hollywood success is trickling down to the NFL -- 'cause a Pro Bowl tight end just booked a role on his new TV show ... TMZ Sports has learned.
Jacksonville Jags star Marcedes Lewis confirms ... he just locked up a gig on "Now We're Talking" -- a scripted comedy about 2 washed up QBs who try to become broadcasters.
The show is being produced by Warner Bros. in conjunction with LeBron's Uninterrupted sports-entertainment network for Verizon’s Go90 mobile-video service.
As for Marcedes' part -- he tells us he plays a pro football player who's taking broadcasting courses in the hopes of landing a gig ... and runs into a bunch of old football buddies trying to do the same.
Lewis says Steelers WR Martavis Bryant will also be in the show ... but brags, "I got extra scenes!"
