Great Britain are one win away from the Davis Cup Finals knockout stage after Dan Evans produced a gutsy fightback to give his side a lead against France.
With a spot in the Final Eight at stake, Evans opened the best-of-three tie by beating Arthur Fils 3-6 6-3 6-4.
British number one Cameron Norrie will secure his team's progress if he beats Ugo Humbert in the second singles.
If Norrie loses and France level, Evans and Neal Skupski can still clinch qualification in the deciding doubles.
Four nations - Britain, Australia, France and Switzerland - are playing in the group stage event held at Manchester's AO Arena.
