Crystal Palace striker Jean-Philippe Mateta was carried off on a stretcher after a collision with Millwall goalkeeper Liam Roberts in the Eagles' 3-1 FA Cup victory. Mateta received 25 stitches in his left ear and was discharged from hospital later that evening. Palace manager Oliver Glasner condemned Roberts' challenge, saying it could have been a career-ending injury. Millwall manager Alex Neil defended his player, saying he did not intend to injure Mateta. In other news, Manchester United head coach Ruben Amorim warned his squad that he will be honest with them about their futures in the summer transfer window. Amorim said he is not ruthless, but he will have to make difficult decisions if he wants to reshape his squad. United are currently 14th in the Premier League and Amorim may need to sell players to buy new ones.
