The 35-year-old was hopeful of continuing his professional career, but he has ruled out a return to the game in the immediate future.
"It has been a difficult time for me mentally and physically," Boucher said.
"I have had two major operations and four blood draining operations in the past three weeks and physically, at times, I have been in a lot of pain.
"It is unlikely that I will play any professional cricket again in the near future, which is very unfortunate as I was looking forward to contributing as a player for the Cobras."
Boucher made 999 dismissals in his international career.
