Graham Potter revealed Oli McBurnie had been ruled out of Swansea City’s draw with Preston after coming down with a fever overnight.
The Scotland striker had missed the FA Cup win at Aston Villa due to sickness, but had been able to return to training in the build-up to the Deepdale clash.
But McBurnie, who has scored 10 goals so far this season, fell ill on Friday and, despite having travelled to Lancashire, was not risked in the 1-1 draw.
“He had a bit of sickness overnight,” confirmed the Swans boss.
“He had a fever overnight, he did not get much sleep.
“He felt a bit better this morning but not enough to take the risk in these sort of conditions and this sort of game.
“So it is disappointing, it was just this morning really.”
