Hugo Lloris, the captain of Tottenham Hotspur, has been ruled out for six to eight weeks due to a knee injury.
The former France captain, 36, suffered ligament damage in Spurs’ 1-0 Premier League win over Manchester City on Sunday.
Spurs’ backup is former Southampton and England international Fraser Forster.
Other options include academy players Brandon Austin and Alfie Whiteman, but neither has much senior experience.
Spurs are currently fifth in the Premier League and vying for a place in the Champions League for next season.
They play Leicester City in the league on Saturday before traveling to AC Milan for the first leg of their Champions League round of 16 tie on Tuesday.
Forster, who joined Spurs on a free transfer last summer, has made just one Premier League appearance for the club, a 2-2 draw with Brentford on Boxing Day.
Last month, Lloris, who led France to World Cup victory in 2018, announced his retirement from international football.
