Bulldogs player David Minute thought moaning and talking like a "boogie man" during a series of phone calls to a female coach was a joke.

But the 22-year-old has lost his NRL contract, his $90,000-a-year salary that supported eight relatives, and is now subject to a good behaviour bond.

Minute appeared in Burwood Local Court on Tuesday, where he was given a 12-month bond for harassing Elizabeth Marin, the team's strength and conditioning coach, during eight calls to her mobile phone.

According to a statement of facts tendered to the court, Ms Marin received several silent calls from a private number about 6.30pm on July 19.
