Worcester's pre-season preparations took an unexpected turn when their team bus caught fire on their way to play Ospreys on Saturday.
The bus was on the M5 travelling to south Wales when the incident occurred.
"The Warriors team bus caught fire on the M5 this morning. Discussions are taking place to determine whether the match will go ahead," a statement on the team's official Twitter account said.
"All players and staff are safe and well. We will let fans know as soon as a decision regarding the match has been made."
The match is the Warriors' final encounter before their season kicks-off against Leicester on September 8.
