The Daily Telegraph reported the news on Monday night, and suggested the club are shopping him around in the hope of an immediate release.
It is believed Hastings doesn’t not fit in with teammates off the field, with the club even offering to help him with counselling.
The players have seemingly got their message through to Barrett, with the Sea Eagles’ squad for their game against the Eels on Sunday to be named without Hastings.
He will likely line up with Manly’s feeder club in the Intrust Super Premiership, the Blacktown Workers.
It is believes the main reason for Hastings’ demise is his “lack of respect for senior players”, with the club confirming an incident between Hastings and Daly Cherry-Evans taking place in Gladstone last week.
The Sea Eagles however did confirm it was not a fight.
Hastings has played four games for the Sea Eagles so far this season, but missed their round six match with an Achilles injury.
The 22-year-old may not remain in the NRL, with English Super League clubs reportedly interested in his services.
It seems as though their is no way back for Hastings now, given the comments of one club insider to The Daily Telegraph.
“He is off with the playing group. There has been a lot of angst at training between Jackson and certain members of the playing group. This has been building up for a couple of weeks now. He just doesn’t fit in here,” the insider said.
“There is definitely a personality issue there. It’s coming across that there is a real lack of respect for senior players. This isn’t a one-off.”
Hastings has played 47 first grade games for Sydney and Manly after making his debut in round 26, 2014 for the Roosters.
