The Cherries seek an immediate return to winning ways after going down 3-2 to Brentford two weekends ago, a game in which Ryan Christie picked up his fifth booking of the Premier League season.
The Scotland international will therefore be unavailable for Saturday's game through suspension, joining Alex Scott (knee), Julian Araujo (hamstring) and Luis Sinisterra (thigh) on the hosts' list of definite absentees.
The Cherries are also waiting to learn whether Milos Kerkez and Antoine Semenyo will be back from their international-related knee concerns, while Dango Ouattara is in the same boat with his adductor problem.
Until Iraola sheds more light on their conditions, both Semenyo and Kerkez might be able to reprise their roles in the XI, as the former comprises part of a rejigged attacking line due to Christie's ban.
Philip Billing or Marcus Tavernier should step in for the Scot, and the latter is likely to get the nod alongside Semenyo, Justin Kluivert and Evanilson, who is out to score for the fourth Premier League game running.
The fit-again Tyler Adams and Lewis Cook are likely to pair up in front of an unchanged backline of Kerkez, Ilya Zabarnyi, Adam Smith and Marcos Senesi, although Iraola has a huge decision to make in goal.
Kepa Arrizabalaga did not cover himself in glory against Brentford after Mark Travers started the win over Manchester City, but the Chelsea loanee appears to be his manager's number one.
Bournemouth possible starting lineup:
Kepa; Smith, Zabarnyi, Senesi, Kerkez; Adams, Cook; Semenyo, Kluivert, Tavernier; Evanilson
