Brisbane Broncos utility Alex Glenn has been forced to withdraw from the Cook Islands Pacific Cup squad due to injury.

Glenn, who finished the season with a niggling groin injury, is expected to have surgery later this week, forcing the 21 year old to stand down as captain of the national squad.

Glenn played 26 games for the Broncos this season after impressing coach Ivan Henjak in the pre-season trials.

It is expected that Glenn will be right for the start of pre-season training next month after the surgery.

The Cook Islands, who play Samoa this Saturday in Cairns this Saturday, have named Tere Glassie as replacement captain.
