Manchester City face an anxious wait over injuries to Gabriel Jesus and Kevin De Bruyne, who were both taken off in the 0-0 draw at Crystal Palace.
Gabriel left the pitch in tears in the 23rd minute after appearing to accidentally injure his knee when he slipped as he tried to control the ball minutes earlier.
De Bruyne was stretchered off after a strong tackle from Palace's Jason Puncheon, who was booked and was also taken off on a stretcher.
But Belgium international De Bruyne was seen walking back to the City dressing room accompanied by two medical staff.
City boss Pep Guardiola told BT Sport: "He [Gabriel] is injured. Hopefully not tough, but maybe one or two months he will be out.
"With Kevin we were lucky. I don't know what happened today. We were lucky in the past. But I don't know what happens in the future."
The draw brought City's 18-game Premier League winning streak to an end to as they finished one win short of Guardiola's record, set at Bayern Munich.
However, they remain unbeaten thanks to a last-minute penalty save from Ederson, who kept out Luka Milivojevic's spot-kick.
Guardiola would not comment on the decision to award the penalty, which came after Wilfried Zaha went down under a challenge from Raheem Sterling.
"Maybe [it was penalty] -- I didn't see it really well," he sad. "But if the referee decided it, it's OK.
"They are a good team. We knew that. The second half was better than the first. We had problems getting going.
"At the end, Ederson helped us to keep one point."
