Lo Celso, who joined Spurs on loan from Real Betis with an option to buy next summer, played 53 minutes of Argentina’s friendly against South American neighbours Chile on Thursday, during which he suffered a knock to his groin.
At the time, the player insisted to local media that it was nothing severe and simply a ‘blow’.
However, it was enough for Lo Celso to withdraw from the squad of the next match against Mexico, and the Evening Standard now reports that Spurs ‘fear’ the 23-year-old has sustained more severe damage that could keep him sidelined for ‘several weeks’.
The London newspaper asserts that Lo Celso is being assessed by Spurs medical personnel, with tests so far leaving staff ‘concerned’ over his fitness.
Tottenham are due to face Crystal Palace at home when Premier League football resumes on Saturday, with this season’s Champions League group stage then to begin with a trip to Greece to face Olympiacos next Wednesday.
They will also play Leicester, Colchester, Bayern Munich, Red Star Belgrade and Liverpool among eight further fixtures in three competitions before the end of October.
Lo Celso is still awaiting his full Tottenham debut, despite having arrived in north London a month ago, having not yet started a game for his new club.
The former Rosario Central and Paris Saint-Germain player has made three substitute appearances in Spurs colours so far, totalling just 44 Premier League minutes.
Frustratingly for Spurs fans, injury has already ruled club-record signing Tanguy Ndombele out of the last two games. Meanwhile, fellow summer arrival Ryan Sessegnon is still to play for the club since joining from Fulham as he continues rehabilitation on a hamstring injury.
