Scott Quinnell and Mark Taylor are major fitness concerns as Llanelli face an injury crisis ahead of their make or break Heineken Cup clash against Northampton Saints.
The Scarlets could be without as many as seven internationals for this Sunday's Pool 4 decider at Franklin's Gardens.
Quinnell retired early from last week's victory over The Borders with a groin strain and would be a major loss after scoring five tries in as many pool games this campaign.
Fellow British Lion Taylor is still struggling with a knee problem picked up in Agen where Irish flanker Simon Easterby also broke a bone in his hand.
"We are just trying to give both Mark and Simon as much time as we can to recover," said Llanelli director of rugby Gareth Jenkins.
There was further frustration for club captain Leigh Davies and Mark Jones who both made their long-awaited return from lengthy lay-offs.
Jones suffered a relapse with his troublesome knee that has kept him out since the World Cup while injury-plagued Davies pulled his hamstring in training.
Meanwhile props John Davies bruised his foot while Iestyn Thomas sprained his ankle while training with Wales on Monday.
The mounting injury list is so acute that Jenkins has been forced to delay both naming his team - and even training - ahead of the club's biggest game of the season.
But it is the injury to Thomas which worsened his mood after complaining about the demands placed upon players by the weekly national training sessions amid a vital week in the Heineken Cup.
"These injuries could not have come at a worse time, it's looking pretty precarious at the moment and we even had to call a halt to training because there were so many that couldn't take part," said Jenkins.
With Liam Williams forced out of the World Cup through injury, lock Luke Charteris and Skills Coach Neil Jenkins say they have to put yesterday's defeat behind them as Wales now look ahead to another physical encounter against South Africa in the quarter-finals of the Rugby World Cup.

Twelve young people have been selected to follow a one year WRU Coach Core apprenticeship programme. Coach Core was set up by the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry as part of the Olympics legacy in 2012 and the Duke of Cambridge was on hand to meet the apprentices on their first day in the job. The programme has been funded by the Hunter Foundation.
The WRU has launched a campaign to create a long term legacy for Welsh club rugby by highlighting the advantages of volunteering. Rhian Edwards, a volunteer at Seven Sisters, has enjoyed many benefits of her volunteering at a grassroots rugby club including being part of the Rugby World Cup volunteer workforce after being nominated by the WRU - and the WRU is asking for more people to develop their 'Welsh rugby roots'.
