Tommy Fraser has landed himself in hot water after a bust-up with Albion assistant Dean White.
The pair were involved in a blazing row after the Seagulls suffered a fourth defeat on the trot.
Fraser was not in the squad but still travelled with the party to Wales. The young midfielder was out on the pitch at the Liberty Stadium immediately after the match, joining in the warm-down, when he was involved in a furious exchange with White.
He stormed off down the tunnel, taking a swipe at a drinks bottle on the way.
Boss Dean Wilkins was conducting interviews with the media at the time, so he did not see the incident.
But he is sure to be told by White and that could have repercussions for Fraser.
Albion lost to a first half brace from on-loan Darryl Duffy for play-off chasing Swansea after Alex Revell headed in his 11th of the season early on.
Wilkins said: "We are disappointed with the goals we conceded. They were gifts, we did not make them work for them at all.
"In the second half, in terms of possession and getting into the final third, I thought we were magnificent."
Albion are six points better off than Bradford, who lost at home to Leyton Orient, towards the foot of the table and have a much better goal difference with two games to go.
Wilkins added: "I don't think we should even be talking in those terms. We should have been firmly cemented at the very least in mid-table."
Bas Savage is set to miss the remaining games at home to Oldham and away to Cheltenham after suffering a damaged medial knee ligament early on.
Sam Gargan scored his 14th goal of the season as Albion under-18s lost 2-1 against QPR.
