John Terry left Swansea's Liberty Stadium on crutches on Sunday afternoon after a collision with Leroy Fer left him writhing in agony in the closing stages of Chelsea's 2-2 draw.
With a huge game for the west London club coming up against Liverpool on Friday evening, fans of the west London club will be concerned that their captain may not be fit for the fixture.
And Terry won't exactly have quelled those concerns on Sunday evening after uploading a photo and a video of the ankle injury.
First, the veteran defender uploaded a photo showing his ankle encased in bandages, alongside three emojis that summed up how he was feeling.
He then followed that up with a video that, seemingly, was meant to give Chelsea fans some better news as he revealed he was undergoing some late night treatment.
However, the mere fact that Terry was having to head to the physio's room so late on Sunday night, rather than wait until the morning for treatment, suggests that the ankle issue is pretty severe.
Speaking in the aftermath of the game, Chelsea boss Antonio Conte didn't seem too concerned with the prospect of losing Terry for any length of time.
“I don’t know the extent (of the injury)," Conte said, via the Mirror. "Tomorrow we’ll see the situation about his ankle. He is a warrior. I’m not worried.”
With Chelsea on a short week as they prepare for a Friday night game that follows their Sunday afternoon fixture, it doesn't give Terry much time to recover if he plans on playing against Jurgen Klopp's men.
And, although the Blues made a late move to bring in David Luiz on transfer deadline day, they can ill afford to be without their captain and leader for such a crunch fixture against an in-form Liverpool.
Conte, Terry and Chelsea fans will be hoping for some better updates in the days that come.
