Ben Doak was left with what appeared to look like a burst lip as Liverpool's UEFA Youth League clash with Porto ended in a furious rammy.
The Reds secured their spot in the next stage of the competition via a penalty shootout following a 1-1 draw in normal time. Jorge Meireles won and converted a spot-kick for the Portuguese side before Melkamu Frauendof levelled in the second period to force the tie to the lottery of penalties. Luca Stephenson scored the decisive shot from 12-yards as Jesus Diaz hit the crossbar.
But things descended into chaos as the Celtic youngster got caught up in ugly scenes as Liverpool went to celebrate their shootout win and passage to the quarter-final. As his team-mates rushed to goalkeeper Harvey Davies, things broke out into a rammy.
