OTTAWA - University of Saskatchewan offensive lineman Jordan Arkko has received a two-year suspension from the Canadian Centre for Ethics in Sport for an anti-doping rule violation.

The CCES said in a release Arkko's urine sample, collected March 3, revealed the presence of GHRP-2, a non-specified peptide hormone.

Arkko, who was the CIS's top rookie in 2011, was provisionally suspended April 25. He exercised his right for a hearing, after which his suspension was upheld.

He can't participate with any organization associated with the Canadian Anti-Doping Program until April 25, 2016.
