Swansea City were beaten 3-1 by Portsmouth at Fratton Park on Tuesday, missing the chance to return to the top of the Championship. Stephen Welsh was helped off with a knee injury during the defeat, and Swansea are waiting to discover the extent of the problem.
Welsh set for scan
Welsh was injured in a challenge by Ebou Adams which saw Adams booked. When asked whether Scotland international Welsh's problem could be serious, Swansea head coach Vitor Matos said: "Of course there is that possibility, but let's first have the scan and then speak about it."
Late swing in the match
Zan Vipotnik's 85th-minute penalty made it 1-1. Ross Stewart hit the bar three minutes after Vipotnik's penalty, before Portsmouth scored two stoppage-time goals to claim victory.
Clash after the final whistle
Players and staff from both clubs clashed in the centre circle after the final whistle. Matos said he was unsure what sparked the melee because he was "already inside".
He added: "Let's say it is not an easy place to come and try to hold the emotions, especially with how the game was."
Matos said: "It's more a situation for the refs to control. It was quite harsh in terms of decisions I would say. It was an emotional game – everyone quite emotional."
He also said: "It was not easy in the first half losing a player with a tackle. Then I would say harsh decisions, really on the limit in terms of cards."
Swansea injuries and table position
Swansea slipped to fourth in the table after a third defeat in their past four matches. Birmingham City replaced Swansea in second place after a 3-0 win over Millwall on Tuesday.
Cameron Burgess is a long-term absentee, while wingers Moussa Yeo and Ronald are also out. Stephen Eustaquio was not involved against Portsmouth after coming off in the win over Blackburn Rovers with a groin problem. Eom Jisung was absent at Fratton Park after suffering what the club described as a contact injury during the Blackburn game.
Swansea will play at Birmingham City on Saturday in their final game before the season's second international break. Matos said: "It's a hard league, so many games to come. We need to stay stable emotionally because it's important for us that we focus on what we need to improve."
