From a penalty, Dan Edwards kicks his side brilliantly to five metres out.
Heavy pressure that follows and moments after coming on, replacement scrum-half Reuben Morgan-Williams throws out a long left-handed pass and Daniel Kasende does well to get over in the corner.
Edwards can't make it a seven-pointer but boy, did the hosts need that.
Some much needed Ospreys possession but after a lineout drive on half-way - the Lions hold things up and get the scrum.
Kieran Hardy was struggling to get the ball back there. The number nine looks away with the face of a man who has been told there's no hot water for showers after the game.
Gavin Coombes isn't often stopped from that distance but the man who has become known as a close-range specialist looked to have been thwarted there.
But, with the on-field decision being a try, there is no angle that shows definitively that the ball was grounded before the line after initially coming down on a Dragons' knee.
