Gareth Hock could leave Salford after his latest disciplinary issues

Former England forward Gareth Hock could leave Salford after the latest controversy which saw him handed a six-game ban.

The 31-year-old was found guilty of two separate offences of kneeing opponents in the defeat by St Helens and handed a three-game ban for each offence.

"It's up to Gareth now," owner Marwan Koukash told Sky Sports News.

"Maybe the time has come for Gareth to see what else he wants to do other than rugby league."

Hock could also be in trouble with the Rugby Football League, which is investigating an alleged breach of discipline relating to a message he posted on his Twitter account this week.

The former Wigan player submitted a transfer request in September but later withdrew it and appeared in Salford's opening two games of the season.
