The Welshman has extended his deal at the Hawthorns until 2019 and admitted his delight at being able to continue the 'building process', as the Baggies eye another top-half finish.
West Brom recorded a 1-0 away win at Crystal Palace on the opening day of last season and also ended a poor recent run against Bournemouth last term. A 2-1 home success in 2016-17 ended a run of four games without a win against the Cherries.
Gareth McAuley scored the winner then but will miss Saturday's match with a thigh problem, while Pulis is also missing midfielder James Morrison due to a knee injury. The Baggies though are expected to hand a debut to summer signing Jay Rodriquez while another new addition, Ahmed Hegazi, is also pushing for a starting berth.
Bournemouth, who have lost both of their opening day Premier League fixtures, will hand a late fitness to Jermain Defoe as the former Sunderland and Tottenham man is battling to recover from a groin injury.
Two other summer arrivals, Asmir Begovic and Nathan Ake, are expected to start but there will be no place for Junior Stanislas, with a groin issue keeping him on the sidelines.
