This would be the first Serie A game to be impacted by the latest wave of COVID cases, prompted by the Omicron variant.
News agency ANSA reports the local health authority (ASL) has ordered Salernitana into quarantine after several positive tests within the matchday squad.
However, a statement from the club made clear there was only one positive test.
They were meant to fly out today to Udine, but were blocked from making the journey on a regular flight.
It is possible the game will go ahead, if the other swabs that come in from the rest of the group are negative.
Those results are expected within a few hours, so the journey could be made tomorrow morning using a private plane.
The Serie A match at the Dacia Arena in Udine is due to kick off on Tuesday at 17.30 GMT (18.30 local time).
