England forward Harry Kane suffered a worrying ankle injury ahead of this year's delayed European Championships after scoring twice in a 2-2 draw away to Everton in the Premier League on Friday. Gylfi Sigurdsson also grabbed two goals for Everton in a result that did little for either side's European hopes. Kane went off in stoppage time towards the end of the match after rolling his ankle when challenged in the box at an Everton corner. "It is too early to say something. For him to leave the pitch with a few minutes to go is obviously because he felt something," said Tottenham manager Jose Mourinho. "Let me be optimistic and believe that he has time to recover. Let's see." The draw left Tottenham without a win in their last three games and stuck in seventh place, five points behind fourth-placed West Ham United who have played a game less. Everton's third successive draw left them eighth, a point behind Tottenham but with a game in hand. Kane began the night level on 19 goals with Liverpool's Mohamed Salah in the race for the Golden Boot. But he moved clear in the 27th minute when Michael Keane failed to cut out a cross and the ball arrived at Kane who took a touch before drilling a shot past Jordan Pickford. Tottenham have struggled to hold on to leads throughout the season and this time their advantage lasted all of three minutes as Sergio Reguilon fouled James Rodriguez in the box and Sigurdsson slotted home the penalty. Everton had good chances to go in front before halftime with Hugo Lloris twice denying Rodriguez. Former Tottenham player Sigurdsson put Everton in front just past the hour mark when he met Seamus Coleman's cross with a sweetly-struck first-time shot. But Everton's defence again blundered and a mix-up at the back allowed Kane to thump in Tottenham's leveller. Richarlison should have won it for Everton at the death but he blazed over the bar with the goal at his mercy. The most significant moment was still to come though as Kane was injured as he challenged for a ball in Everton's area. He limped off and was replaced by Dele Alli but Tottenham fans will be fearing that he could miss next weekend's Wembley clash with Manchester City.
