They talked about it, that's when he reaggravated it. They spoke about aggravating it earlier in the game, likely from the play in the OP.
Wonder if the Jazz announcing crew said "Harden trying to flop, no call." Sucks how Harden is considered a big-time flopper (which he isn't), yet the refs and fans won't be interested in accepting that he got tripped on that play (twice, actually). Not to say it should be a foul (big guys have naturally wide stances), but it certainly isn't a flop, as Harden is trying to get around Gobert to front him. Got to love Gordon for throwing his hands up to complain, yet didn't even see what happened.
I've noticed early on, that so far early in this season, gordon is in love with throwing his arms up.
