He has played one game in over two months, but returning New South Wales winger Brett Morris says he knows exactly what it takes to compete at State of Origin level.
Morris was one of two changes announced by the Blues when the team was named for their clash in Melbourne next Wednesday, with Roosters giant Daniel Tupou the man to make way.
Morris made a successful comeback in the Bulldogs' 29-16 win over St George-Illawarra on Monday in what was his first game since injuring his hamstring in Round 5.
But the 28-year-old allayed any fears he was heading into the vital match underdone.
"Obviously with the injury, I did a lot of training ... so the fitness is all right. It's just the match fitness," he said. "But I have played enough footy now over the years to know what I have to do in games so I'm confident I'll be going out there 100 per cent."
