Chelsea striker, Tammy Abraham, was led away on a stretcher before half-time during Chelsea’s 2-2 draw at Valencia.
The 22-year-old sustained the injury after landing awkwardly on Valencia defender Ezequiel Garay.
He told Chelsea TV: “It’s much better than when it happened.
“I was fearful of the worst when it happened but when got into the changing room, I could walk about. I’ll have a scan and hopefully it’s just bruising.”
The draw means Chelsea will not know their Champions League fate until the final group games.
The Blues looked set for a place in the last 16 after Christian Pulisic gave them a second-half lead and Kepa Arrizabalaga saved Daniel Parejo’s penalty.
But with eight minutes remaining, Daniel Wass’ intended cross from the right bamboozled Kepa, who appeared to misjudge its flight.
Maxi Gomez had missed two opportunities from close range for the home side before Carlos Soler gave the Spanish club a 40th-minute lead when he converted Rodrigo Moreno’s cross.
However, Chelsea equalised 108 seconds later as Mateo Kovacic turned at the edge of the area and struck a low effort into Jasper Cillessen’s right-hand corner.
