An Irish cyclist has been banned for four years for an anti-doping violation, Cycling Ireland and Sport Ireland announced today.

Dale Walker "tested positive for the presence of the following prohibited substances: epioxandrolone, oxandrolone, 18-noroxandrolone and boldenone and/or boldenone metabolite(s)," a joint statement from the two bodies said.

The test was conducted following Walker's participation in the Masters Road Race Championships in September last year - which Walker won. He has subsequently been disqualified from the event.
