Guinness Premiership new-boys Leeds Carnegie have suffered a double injury blow after just one game back in the top flight.
Fly-half Alberto Di Bernardo and Hendre Fourie, who were both part of the club's summer recruitment drive, are set to be out of action for at least a month following the 49-24 defeat to Gloucester.
Scans have shown that former Rotherham flanker Fourie has torn a bicep, while Di Bernardo, who signed from Cornish Pirates, has broken a bone in his hand.
Director of rugby Stuart Lancaster told the club's official site: "It is disappointing news for both Hendre and Alberto as they have trained so hard in pre-season to play in the Guinness Premiership.
"Both players looked more than capable at this level before they had to come off and I am sure they will be back as soon as possible.
"We will look at our options this week during training before we head to Harlequins on Saturday but we have every confidence in our squad.
"This is the strongest squad we have ever assembled at Leeds and that is a vital factor in a competition as tough as the Guinness Premiership."
