Tottenham Hotspur winger Andros Townsend will be assessed by club officials after going off in the goalless Europa League draw against Partizan Belgrade with a leg injury.
Townsend was replaced by Erik Lamela after 59 minutes in Serbia after suffering a dead leg following a challenge which left the England international sprawled on the turf in clear pain.
The 23-year-old has avoided picking up a muscle strain but is still a doubt for the Premier league visit of West Bromwich Albion on Sunday, with Pochettino admitting the club will know more about his availability in the next 24 hours.
"Andros has a problem with his leg," said Pochettino after the game. "It could be his glute, and Friday we'll know if he's available or not."
Having missed the back end of last season and the World Cup finals with an ankle injury, Tottenham will be hopeful Townsend can make a swift return to the first team.
The injury marred an impressive away performance from Spurs which saw their unbeaten record in the Europa League group phase extend to 13 matches after picking up an impressive point against last season's Serbian Superliga runners-up.
Harry Kane hit the bar in the first minute for Tottenham from a tight angle, however the remainder of the game saw the north Londoners pushed onto the back-foot as captain Hugo Lloris saved from Danilo Pantic, while Jan Vertonghen twice came to the recuse with goal-saving challenges.
It leaves all four teams in Group C level on one point, after Besiktas were held by Asteras Tripoli, following the opening round of fixtures, leaving Tottenham boss Pochettino content with the outcome.
"It was a tough game," said Pochettino. "We talked yesterday about this game and that it would be difficult and in the end, a draw is a fair result.
"We competed, kept a clean sheet but we wanted the three points.
"It's important not to lose these games, of course. It was difficult but we need to look forward and look at the positives, like Fazio and Stambouli making their first starts for us. They did very well.
"Now we need to look forward and prepare for West Brom on Sunday."
