With Canterbury's Brett Morris sidelined by a knee injury, Fairfax Media understand that Daley plans to pick Hopoate over South Sydney's Alex Johnston after being told of similar concerns from the Eels camp last season about his fitness. Hopoate, who made his Origin debut while a rookie at Manly in 2011 before leaving the game for a two-year Mormon mission, replaced Morris on the wing in the second game of last year's series after the Test winger and his twin Josh had both heroically ignored serious injuries to help the Blues win the series opener. However, the 23-year-old also suffered a shoulder injury that required pain-killing injections for him to remain on the field in NSW's series-clinching 6-2 victory that ended Queensland's eight-year domination and he missed the third Origin in Brisbane. Should the Blues medical staff have any doubts about Hopoate's groin injury, Johnston is expected to be called in to replace him after making his Test debut for Australia in the 26-12 Anzac Test loss to New Zealand. After scoring 19 tries in 16 matches for Souths last season, the 20-year-old has crossed for eight tries in 10 matches so far this season.

But the fact that Johnston usually plays on the left wing for the Rabbitohs is a reason he is leaning towards Hopoate as Sydney Roosters winger Daniel Tupou is set to retain that position and maintain his left side club combination with centre Michael Jennings. Josh Morris will be right centre, with St George Illawarra's Josh Dugan at fullback. Daley also has other fitness concerns to check on before finalising his team ahead of Tuesday's announcement after secondrower Ryan Hoffman was concussed for the second time in three matches for the Warriors and utility Luke Lewis suffered respiratory problems during Cronulla's 23-22 win over Gold Coast . A groggy Hoffman had to be assisted from the field in just the third minute of Saturday night's win at Parramatta Stadium and Warriors doctor John Mayhew said he would need to go through the standard NRL concussion protocols before a final decision could be made on his availability for Origin 1. The 2014 NSW player of the series, said, however, that the head knock wouldn't keep him out of the series opener.

"I feel completely fine and feel there will be no problems," Hoffman said after the match. He later tweeted: "Thanks everyone for their concern but I'm fine. Bit of a bump but I'm ok. Outstanding win from the boys. TOUGH win!!!" Lewis is also confident of being fit after suffering breathing problems caused by complications from the medication he has been taking after a thyroid cancer scare last year. While there are suggestions that his position was under threat from Sharks teammate Andrew Fifita, Cronulla coach Shane Flanagan believes Lewis' big match experience will be invaluable for the Blues. The 31-year-old has made 17 Origin appearances for NSW since his debut in 2004 and will be the most experienced member of the Blues side after the withdrawal of captain Paul Gallen with a hip injury, suspension of Greg Bird and loss of Jarryd Hayne to NFL.
