Cameras caught Harry Kane slowly limping off the pitch after 90 minutes at Wembley Stadium on Sunday after Spurs fell 1-0 to Manchester United.
The big English striker walked gingerly to the tunnel following the match.
Kane was caught on the left foot by United center back Phil Jones deep into stoppage time, and stayed prone on the pitch for the final few moments.
Early reports say the injury is to his left ankle, and Spurs boss Mauricio Pochettino is not pleased with Jones.
Pochettino, “It was a bad tackle on Kane and there is a little bit of swelling, I don’t think it was intentional. It’s a worrying thing because we’re going to lose Son to the Asian Cup and if Kane is suffering an issue it will be a massive problem for us.”— Chris Winterburn (@cmwinterburn) January 13, 2019
