Tottenham will be without defender Toby Alderweireld when they host Ludogorets in the Europa League on Thursday.
Spurs are top of Group J on goal difference, with three teams level on six points after three matches.
Belgium international Alderweireld, 31, suffered a groin injury in the 2-0 win over Manchester City on Saturday, but it is not as bad as first feared.
“He has a muscular injury but not as big as we initially thought,” said Spurs boss Jose Mourinho.
“He will have time to be out, but not like a month which was immediately what we thought. I would say between two and four weeks.
“It’s bad news. He was playing his best football. He’s an important player that we’ll miss.”
Republic of Ireland full-back Matt Doherty is available again following a positive coronavirus test while on international duty, but Mourinho says forward Erik Lamela remains absent with a foot injury.
There had been doubts over the match taking place, with reports in Bulgaria suggesting some Ludogorets players had tested positive for coronavirus.
“According to my information, that’s not true,” said Mourinho. “The problems they had were immediately after the game we played there [a 3-1 win on 5 November].
“They have had one more game after that, which they won, then the international break.
“Of the team that comes, I believe only two players who played against us are not playing. Apart from that, the other nine are in the list and ready to play.
“I don’t understand the news. There is a big contradiction between the news and the information we have.”
