This time it's the Scarlets who will look to the TMO. There looked like a lot of bodies under that ball, but what will the TMO make of it?

It is fair to say not everyone watching the game agrees with the TMO's decision, even Ospreys fans...
Ed: Oof! If I were a Scarlets supporter I’d be a bit miffed with that! However, I’m not so I’ll take it!
Try - Scarlets 7-12 Ospreyspublished at 33 mins
George North
After a long deliberation with the TMO the try has been given and the Ospreys have turned the game of its head. Sam Davies misses the conversion from a difficult angle, but the travelling Ospreys fans do not look too concerned. They deserve the lead.
