John Brain is ready to make late calls on the fitness of kicking kings Shane Drahm and James Brown ahead of the trip to Gloucester - but Marcel Garvey is definitely ruled out a return to Kingsholm.
Director of Rugby Brain has revealed that Drahm and Brown are both doubts for the huge Guinness Premiership fixture.
He has vowed to give the duo time to prove their fitness before naming his team for the crunch clash.
However, Brain has revealed that flying wing Garvey will not be able to make a return to his former club after picking up an injury against Leicester Tigers.
"James Brown went off with a back spasm during Tigers, that has improved but he hasn't trained yet and we won't make a decision on him until Friday," he said.
"Shane Drahm also picked up a hamstring strain in training, it is not torn but we have got to treat that.
"There is a chance that we could be without both of those players and that would be a blow for us - but neither are ruled out.
"Both have better than a 50-50 chance. We will take it day-by-day and not make any calls until late in the week.
"If they are ruled out Simon Whatling would be fit and available to come in and we also have 'A' team player Joey Carlisle."
"Marcel Garvey has fractured his right eye socket and will be out for between four and six weeks," he added. "It doesn't require surgery but he will still be out for that period of time."
Premiership Rugby today announced an extension of their partnership with the UK's largest insurance company, Aviva, for a further three years. The contract extension, which starts in the 2014-15 season, will cover a golden era for club rugby in England and will include a period when the country will host a Rugby World Cup and when rugby union will finally rejoin the Olympic movement.
Not only are the great and the good of the Aviva Premiership Rugby strutting their stuff at Twickenham this Saturday - so are the new generation of rugby players, including Worcester RFC, courtesy of the Land Rover Premiership Rugby Cup.
Warrior Stuart Brooks will represent the club at Twickenham next weekend as he battles for the honour of carrying the coveted Aviva Premiership Rugby trophy onto the pitch ahead of the final between Leicester Tigers and Northampton Saints.
