Former Richmond footballer Jake King is set to make a deal with prosecutors over an alleged extortion attempt amid concerns he could lose his job over new steroid charges.

On Tuesday, the ex-AFL player faced Melbourne Magistrates Court, where his lawyer Geoffrey Steward revealed the 33-year-old has been charged with two new steroid offences.

Mr King also faces charges of extortion, making threats to kill, and threatening to inflict serious injury against Tony Mokdissi in May 2017.

The former forward allegedly threatened to shoot and break Mr Mokdissi's legs and those of his family if he did not pay Mr King $150,000 within four weeks.
