ERC can confirm that the Federation Française de Rugby (FFR) has withdrawn its application to host the 2014 Heineken Cup and Amlin Challenge Cup finals, due to the ongoing uncertainty regarding the availability of the Stade de France.
The Yorkshire side met favourites Bath in the Twickenham final and suffered a major setback when in-form Balshaw limped from the field after 25 minutes.
British Lion Balshaw had been struggling all week after tearing a quad muscle strained in training and his insistence in featuring in the Twickenham triumph could cost him a place in the Worcester clash.
"It felt OK in the warm-up but when I had a run and tried to kick on a bit, I just felt a bit of a pop," said the full-back .
"Obviously, there is a bit of worry there. I wasn't 100% really, but I desperately wanted to play."
Leeds coach Phil Davies will now sweat on the results of a scan to see how long he will lose his skipper for but it's doubtful Balshaw will make it back in time for Friday night's clash at the Sixways Stadium.
