Wests Tigers fans will have to wait for their first look at Lachlan Galvin, with the youngster ruled out of the club's opening Pre-Season Challenge match.

Set to compete against the New Zealand Warriors, the club confirmed that Galvin has been ruled out after sustaining a calf injury in training leading up to the game.

While his return date is unknown at this stage, the five-eighth will return to Sydney and "will undergo scans on what is said to be only a minor strain".

In his place, talented young halfback Iverson Matai will enter the squad. Matai, who is a member of the extended NSW Cup squad, was recruited from the Canterbury Bulldogs last year and was a member of the team's SG Ball Cup and Jersey Flegg Cup in 2023.
