The Forest captain was stretchered off and is now in hospital.
Jamie Ward was the hero for Forest, as the summer signing from local rivals Derby County scored his first goal for the club to condemn Jimmy Floyd Hasselbaink to yet another defeat as QPR boss.
But it was a result that might have come at a price.
Forest captain Henri Lansbury looks to have suffered a serious ankle injury. The midfield maestro had to be stretchered off at the City Ground and the fear is he may have broken the joint.
That fear was confirmed by Forest manager Dougie Freedman.
He told BBC Radio Nottingham that he was hoping for just a sprain, although sounded fearful:
"Hopefully it's just a sprain in his ankle, rather than a break. He twisted on his ankle. He's going to hospital."
It would be yet another injury blow for Forest. Dani Pinillos was recently ruled out for the rest of the season with an ACL injury whilst Britt Assombalonga, Matty Fryatt and Andy Reid are all still on the sidelines.
Forest fans will be hoping that their captain is not as seriously injured as it first appeared.
