Cowboys captain Michael Morgan has ruled himself out of the State of Origin season after a shoulder injury that left him playing only six games this year.

This comes before Manly star Tom 'Turbo' Trbojevic was told he has the responsibility of following Morgans lead.

Reporter Chris Garry said on Monday that 7 News had announced Morgans withdrawal from this years series after a "nagging shoulder injury" left him with no other choice.

The attention now draws to Trbojevic who returned on the weekend from a hamstring injury suffered in Round 6 only to suffer a shoulder injury upon return.

With the injury ruling him out of the final game of the season, the Sea Eagles coach Brad Fittler told the fullback: โ€œitโ€™s official mate, if you stop sooking youโ€™re the first person in the squad of 27,โ€ onย The Sunday Footy Show.

Yet, Paul Kent toldย NRL 360 that it was "unfair" to play the 23-year-old in such a physically demanding series after he has had such little game time this year.

โ€œManly have no choice. Theyโ€™re not allowed to pull him out and theyโ€™re not allowed to tell Freddy not to pick him,โ€ he said.

โ€œI donโ€™t think he should play though... I think itโ€™s unfair on Tom.

โ€œI think the fact is when Origin rolls around he would have played one game in 19 weeks, he was underdone on the weekend and youโ€™re asking him to go into an Origin game underdone.

โ€œSecond to that, if we go back and look at the horrific injury toll thatโ€™s happened this year, most people will put that down to the fact that when the game resumed there was a lack of preparation as far as off-season training.

โ€œYouโ€™re going to ask this guy to go through that and come into an Origin game underdone and expect his body to hold up.

โ€œHeโ€™s got to give himself every chance and he needs to go into pre-season training in that November period, rather than an Origin camp.โ€

Co-host ofย NRL 360 Ben Ikin agreed with Kent saying that it would be "deeply concerning" for Manly coach Des Hasler if Trbojevic was to play the Origin series.

โ€œIf the six-again rule has made the home and away rounds much faster, can you imagine what it will do to Origin?

โ€œSo if youโ€™re coming off no prep and playing State of Origin particularly in the shape his body is in at the moment, that would be deeply concerning for Des Hasler.

โ€œIf Iโ€™m the sea Eagles right now, Iโ€™m considering all forms of special treatment to get this player right for next year because we have seen how Manly perform without their star fullback isnโ€™t on the field.โ€

The Daily Telegraphโ€™s Buzz Rothfield continued, adding that Trbojevic "nearly owes itโ€ to his club after spending so much time on the sidelines this season.

โ€œI think Des and the medical team at Manly have got to have a chat and say โ€˜look we know you want to play Originโ€™... but you know what, heโ€™s on $900,000 at Manly and heโ€™s played seven games this year,โ€ Rothfield toldย NRL 360.

โ€œHeโ€™s got to get his body right, heโ€™s got to be ready to go in February, March next year.

โ€œI think he nearly owes it to the club, no one can question his loyalty to Manly but I think heโ€™s got a responsibility to them to ensure that heโ€™s fully fit next year and Origin is not going to help.โ€

Kent believes that Trbojevic is likely to skip the series - with Manly's intervention - to be fit and healthy for the 2021 season.

โ€œI think Manly will make a sneaky phone call to Brad Fittler and at some point after a discussion with Tom there will be a subtle announcement that heโ€™s probably going to go get his body fit for next season rather than play Origin.โ€

The Blues without some Turbo action is going to be a sad sight to see for Origin fans but Ikin responded saying: โ€œI know heโ€™s a star but itโ€™s not as if Brad Fittler doesnโ€™t have options.โ€

Broncos star Kotoni Staggs, Dragonsโ€™ Zac Lomax and veteran Josh Morris have been counted as options to take Trbojevicโ€™s place in the centre position it was expected he'd be picked for.
