Ulster head coach Neil Doak has warned his players not to get caught cold by Oyonnax in the south of France.
The 1999 champions are second in Pool 1 on nine points, while the French side, currently second from bottom of the Top 14 with nine defeats in 12 games, are already out of contention in the Champions Cup.
But that fact has prompted Doak to issue a warning to his men ahead of Sunday’s game (1pm, live on RTÉ Radio 1 Extra or Longwave 252).
“They’ve got nothing to lose, they’re probably going to throw everything at it,” Doak told RTÉ Sport.
“In rugby you can’t look too far ahead. We’ve got to make sure we’ve a disciplined performance.
"Away from home, it’s going to be difficult.”
