Kamara signed on loan with Norwich in January and has netted just once in his eleven outings for the club.
Robb Heineman, CEO of Sporting Club said that the Canaries had declined the option to extend Kamara's stay.
Kamara took to Twitter to thank the club and supporters. He said: "I want to thank the Norwich City organisation for everything they did for me. Not everyone gets to live their dreams, but they gave me mine.
"Also thank you to all the fans in the UK especially in Norwich, Norfolk for welcoming me with warm arms. Top class people/fans.
"Will always have a place in my heart for Norwich. #HeartShapedHands to all u guys & I wish the boys best of luck in next 2 weeks. God bless."
Kamara could return for Sporting as soon as Wednesday against the Seattle Sounders.
