Earle will undergo reconstructive surgery next week.
That bruising encounter with the Saints has also ended rising star Cadan Murley’s season.
The club confirmed he dislocated his elbow in a tackle in the match, which was subsequently successfully relocated.
However, the nineteen-year-old winger will undergo explorative surgery next week with a consultant to assess the injury further.
With his blistering pace and strength in contact, Cadan has made an immediate impact on the fortunes of the side this season. Scoring three tries from his twelve appearances, he continues to excite fans wherever and whenever he plays.
Head of Rugby Paul Gustard lamented this latest injury: “We are disappointed to lose Cadan for the rest of the season as he recovers from a nasty dislocation of his elbow.
“He has impressed us all with his performances this season and has deserved the opportunities he has been given as he consistently shows the coaches and his peers his desire to compete and improve. He trains hard and has a maturity about his career that belies his young age.
“When you reflect on a season there are moments that instantly spring to mind which a put a smile on your face and quite a few of those for me have come from Cadan – perhaps none more so than the try he scored against Worcester in the Quarter-Final which is a finish any top winger in world rugby would be proud of, and indeed hope to be capable of themselves.
“I know that Cadan will be disappointed to miss the end of this season and the junior World Cup but he can be rightly proud of his achievements this year and use this as a springboard for physical development for next season. Like any of our injured boys we wish him well in his recovery.”
