Canterbury fullback Brett Morris will have a fitness test on Sunday to determine if he will make his comeback from a hamstring injury against St George Illawarra.

Morris must take on his former club at ANZ Stadium on Monday afternoon if he is to prove his fitness for State of Origin II.

He has not played since the Bulldogs’ memorable Good Friday loss to South Sydney in round 5.

“He’ll have a fitness test today and we’ll see how he pulls up,” Canterbury coach Des Hasler said on Sunday.

“But more important is how he wakes up in the morning. If he wakes up okay then we’ll make a call sometime during the course of tomorrow.”

Morris trained with the Bulldogs squad throughout the week and is considered a strong chance of taking the field.

His return would not only be a boost for the Bulldogs, who have missed his leadership and attacking spark at the back, but for NSW coach Laurie Daley as well.

After being one of NSW’s best last year, Morris missed the Blues’ Origin I loss to Queensland and will come straight into the line-up for Origin II in Melbourne on June 17.

“It was an unusual hamstring injury so it’s one that we’ve had to treat differently and make sure we’re ticking all the squares,” Hasler said.

If Morris does return, it will mark his first time coming up against his junior club since making a big money switch to Belmore this season.

He missed the sides’ round six clash due to injury and Hasler said coming up against the Dragons was not a factor in Morris wanting to get back out on the park.

“I think he just wants to play at the end of the day,” Hasler said.

“When you’re a player of his ilk, anyone who has been in that situation that’s been out for any length of time, just wants to get back out on the field and play some footy.”
