A minute or so earlier Horo had taken a belt around the head, stayed down or at least was really slow to play the ball, but got nothing from the ref, dunno who it was, probably Bird if I had to wild guess, but it was worth staying down for.
Soon after was the tackle on Garcia, which on the replay didn't look like much but he stayed down and made a bit of a fuss.
I imagine Horo was a little frustrated and ended up being on the end of a penalty for the Garcia thing, so...yeah, he needs a bit of coaching on control cos these things are gonna happen and we don't want him blowing a gasket and seeing cards....shades of catalan.
I don't think there was anything in the Garcia tackle, Horo made it look worse than it actually was and Garcia made a meal of it but it ain't gonna take a lot more to end up in the dugout for 10, or worse.
