Spurs' Europa League comeback spoiled by serious-looking injury to Gareth Bale A distressed Gareth Bale is treated for an ankle injury during Tottenham's Europa League quarter-final first-leg draw with Basel at White Hart Lane. Chelsea's Fernando Torres is congratulated by teammates after scoring his team's third goal in a 3-1 Europa League quarter-final first-leg victory over FC Rubin Kazan at Stamford Bridge . TOTTENHAM suffered a potentially serious setback as Gareth Bale was stretchered off with an ankle injury in the final moments of a 2-2 draw against FC Basel in the Europa League quarter-final first-leg. Bale, who has been in superb form this season, clutched his leg in agony after being stepped on by David Degen in stoppage-time at White Hart Lane and was eventually carried down the tunnel for further treatment. If Bale, scorer of 27 goals for club and country this term, is sidelined for a lengthy period it would be a huge blow for Tottenham, who are battling to qualify for next season's Champions League via a top four finish in the Premier League. Andre Villas-Boas's team are currently third and face a crucial clash against Everton on Sunday. Bale comes off on a stretcher as Spurs draw with Basel. Bale's injury capped a frustrating evening for Spurs, who had to settle for a draw after falling two goals behind following a poor start against the Swiss champions. Valentin Stocker opened the scoring after 30 minutes and Fabian Frei headed home the second five minutes later. Togo striker Emmanuel Adebayor reduced the deficit from close range five minutes before half-time and Gylfi Sigurdsson's deflected 58th minute strike drew Spurs level. Meanwhile, Fernando Torres scored twice in a game for the first time in four months as European champions Chelsea claimed a 3-1 win over Rubin Kazan at home in the first leg of their quarter-final. In Portugal, Benfica came from behind to beat Newcastle 3-1, while Fenerbahce scored two late goals to claim a 2-0 victory over 10-man Lazio. The second legs take place next Thursday.
