Marshall, 38, was originally expected to take over from Tim Sheens in 2025 – who he has been assistant coach and understudy to since the start of pre-season, as part of a plan Tigers’ boss Justin Pascoe said was designed to get “Wests Tigers DNA surging through the club”- but will now step into the legendary coach’s shoes ahead of schedule, after the club announced Wednesday that Sheens would step down by “mutual agreement” at the end of this season.
