Ireland star Evan Ferguson limped off in Brighton's 2-1 win over Liverpool in the FA Cup after a horror challenge from Fabinho.
Ferguson, 18, hobbled off the pitch after Fabinho lunged in with his studs down the back of the right leg of the Meath native.
The challenge happened in the closing stages of the match at the Amex Stadium, with Karou Mitouma scoring the winner to knock the defending champions out of the cup minutes later.

Liverpool midfielder Fabinho was awarded a yellow card for the challenge but seemed very lucky to escape a red.
Ireland and Brighton will be nervously waiting to learn the extent of the injury damage to the young striker who has shot onto the scene this season.
Ferguson impressed again with his holdup play, pace and power on Sunday as he started the match on the back of grabbing a late equaliser for Brighton against Leicester City the previous weekend.
The Bettystown youngster already has three Premier League goals to his name and looks set to be a big part of Stephen Kenny's Ireland plans for the European Championship qualifiers, which start with the visit of France to Dublin on March 27.
