Steven Gerrard has been ruled out of Liverpool's Champions League trip to Lyon, but striker Fernando Torres will be on the plane that heads for France on Tuesday.[LNB]Although Gerrard has now played just 25 minutes of five matches since he sustained a groin injury while on England duty, boss Rafael Benitez has delayed any decision on whether his captain needs an operation.[LNB]Club sources suggest that Benitez is happy that Gerrard's treatment is progressing well and that the player's injury problem is improving.[LNB]If Gerrard does have an operation on his groin, it will rule him out for a month and he would be unlikely to play again until mid-December.[LNB]Liverpool are trying to avoid that eventuality, and Benitez will assess the midfielder's fitness levels again when the Anfield men return from Wednesday's match.[LNB]Gerrard will then have more intensive treatment ahead of the club's next league match, at home to Birmingham on Monday.
