The 23-year-old American joined the Scorchers this season and quickly became a fan favourite with his rebounding ability, selflessness and energy on both ends of the floor.
Jamison picked up a minor ankle injury after Christmas that requires a period of rest.
Due to the time frame of the rest required and the duration of the season still to play, both parties have come to a mutual agreement for Saiquan to return home and focus on rehabilitation.
Head Coach Raftopoulos said: “Saiquan came to this team and executed his role. It is the first time that Scorchers have had somebody lead the league in rebounding.
“I have no doubt in that if we had him for the full duration of the season without the niggles and injuries we have been fighting with as a team, we would be in a different position.
“He is somebody we will do all that we can to hopefully re-sign for next season but for now it is best for him to take some time off and recover from his ankle sprain”.
Jamison commented: “I would like to thank the Surrey Scorchers organization for the great experiences here in England, not the ending I was hoping for at all.
“Thank you to Coach Creon for believing in me from Day one and blessing me with this opportunity to create another chapter in my career. It hurts the most to leave the fans, some of the most loyal fans I’ve been around”.
Scorchers would like to thank Saiquan for his contributions on and off the court during his time at the club.
