Tottenham Hotspur midfielder Rodrigo Bentancur has undergone surgery on his right hamstring after suffering an injury during the 3-2 Premier League loss to Bournemouth last week.
British media reports said the Uruguayan may be out for three months.
Spurs are also without attacking midfielder James Maddison due to an ACL injury, and fellow midfielder Lucas Bergvall also picked up an injury during the Bournemouth game and missed the weekend's 2-1 FA Cup loss to Aston Villa.
"We can confirm that Rodrigo Bentancur has undergone surgery on his right hamstring... and will now commence his rehabilitation with our medical staff," Spurs posted on X on Tuesday.
Media reports also said that Spurs are in talks to sign England midfielder Conor Gallagher from Atletico Madrid to boost their bid for a top-eight finish in the Champions League in order to qualify directly for the last 16.
