Tottenham will be without central defender Toby Alderweireld for their Champions League trip to Bayern Leverkusen on Tuesday.
The Belgian had a scan on Monday after being taken off on a stretcher during Saturday’s 1-1 draw with West Brom.
“We need to wait for the scan but we believe it’s not a big issue,” said Spurs boss Mauricio Pochettino.
Right-back Kyle Walker has been rested, while striker Harry Kane remains out with an ankle injury.
Alderweireld could be replaced by defensive midfielder Eric Dier, who came off the bench to replace him at centre-back against the Baggies.
“The important thing is we trust in him,” said Pochettino.
“It’s not important the position he will play – midfield, centre-back or full-back – we believe and trust in him.
“We trust him as a person and his skills. For me, Eric is a player who can develop his game in different positions.”
Leverkusen games ‘key’
Tottenham are second behind Monaco in Group E on three points, while Leverkusen – in third – have two.
Tuesday’s game is the first of back-to-back matches against the German club which Pochettino believes will be crucial in deciding how far his side progress.
“It’s important, we must win,” said the Spurs boss.
“If we want to go to the next round, this is key to take three points from this game and to play at Wembley the same way.
“The next two games against Leverkusen for us hold the key to the possibility of going to the next round.”
