The 20-year-old was regarded as one of the most exciting talents at the club, capable of playing on either side of defence and in midfield.
The youngster collapsed in training earlier this season with a kidney problem identified as the problem.

Rumours later surfaced that he had once again broken down in training with a career in the professional game seriously in doubt.
