Tottenham goalkeeper and captain Hugo Lloris has been ruled out for six to eight weeks with a knee injury.
Spurs have former Southampton and England international Fraser Forster as a replacement.
Academy players Brandon Austin and Alfie Whiteman are other options, but neither have much senior experience.
Spurs are currently fifth in the Premier League and are fighting for a Champions League spot for next season.
They face Leicester City in the league on Saturday before traveling to AC Milan for their Champions League round of 16 first leg on Tuesday.
Forster, who joined on a free transfer last summer, has made just one Premier League appearance for Spurs – a 2-2 draw on Boxing Day with Brentford.
Lloris, captain of France to victory in the World Cup in 2018, announced his retirement from international football last month.
He has kept seven clean sheets in 21 league games this season.
