Tottenham manager Mauricio Pochettino confirmed striker Harry Kane will be sidelined by ankle ligament damage, but did not say how long he would be out.
Kane, 23, scored the winner against Sunderland at White Hart Lane on Sunday but twisted his ankle while tackling Papy Djilobodji late in the match.
"We will continue to assess him every day but don't want to put a timeframe on it," Pochettino said.
Spurs, third in the league, travel to Middlesbrough on Saturday.
