Everyone watches hockey for the fights ... and last night, the L.A. Kings announcer did his part to set up Keyshawn vs. Bieber by calling out JB during the live broadcast.
Right before the 3rd period, the camera found Bieber and some pals sitting rinkside at last night's Game 7 between the Kings and the Sharks (Go Kings Go!).
The announcer -- clearly abreast of the whole "Keyshawn Johnson vs. Justin Bieber Showdown in Calabasas" -- had a personal message for Key ... come and get him, HE'S RIGHT HERE!!!!
Unfortunately, Keyshawn didn't show up ... we're guessing he's not a big hockey fan.
