Hathras' lacklustre return to racing has cost the imported stayer his manhood.

One of the early favourites for the Group One Metropolitan Handicap, Hathras has performed dismally in two runs since the autumn, finishing towards the tail of the field both times.

Hathras was rated a genuine spring chance after his close-up midfield run at weight-for-age in the BMW during a debut Australian campaign which netted Rosehill and Warwick Farm wins.

Trainer Kris Lees told Racing NSW stewards on Thursday the horse will be gelded.

Racing's unkindest cut will rule the five-year-old out of the spring carnival with Lees deciding to send the son of Dansili to the spelling paddock.

Hathras raced three times in Germany for a win and two placings before his sale to syndicators Australian Bloodstock.
