Antonin Kinsky is set to start in goal for Tottenham's home Premier League game against Nottingham Forest on Sunday as first-choice goalkeeper Guglielmo Vicario is to have surgery on a hernia problem.
Spurs interim boss Igor Tudor controversially replaced Kinsky with Vicario in the 17th minute of their Champions League last-16 tie at Atletico Madrid on 10 March - which they lost 5-2 - after he conceded three goals.
The 23-year-old was consoled by several team-mates, including Vicario, as he made his way off the field.
The other option for Tudor is third-choice goalkeeper Brandon Austin, 27, who came through the club's youth system and has made three senior appearances.
Tottenham said Italy international Vicario will undergo "a minor procedure" next week and hope to have him fit again by April.
The club said the operation had been "timed" for the international break in order to "have as minimal impact as possible".
"Guglielmo will commence his rehabilitation with our medical staff immediately, and it is hoped that he could return to action within the next month," added a statement from Spurs.
