Tottenham Hotspur's Andros Townsend may miss Sunday's Premier League visit of West Bromwich Albion.
The England winger was substituted after an hour of the Europa League draw with Partizan Belgrade on Thursday after suffering a dead leg in the second half.
His fitness is being monitored by Tottenham's medical staff as they prepare to welcome the Baggies to White Hart Lane.
Kyle Walker is definitely out with an abdominal injury, but Spurs boss Mauricio Pochettino will be able to call upon Younes Kaboul, Danny Rose, Mousa Dembele, Nacer Chadli and Emmanuel Adebayor again after resting them in midweek.
Townsend has only played 60 top-flight minutes for Spurs this season and is yet to start a game.
