Bournemouth could be without top scorer Dominic Solanke, who injured his ankle during the midweek win against Stoke.
Chris Mepham, Lloyd Kelly, Alex Scott and Emiliano Marcondes are still absent but fit-again summer signing Tyler Adams might make his league debut.
Bukayo Saka, Declan Rice, Leandro Trossard, Gabriel Martinelli, William Saliba and Fabio Vieira are all injury doubts for Arsenal.
They remain without Thomas Partey and long-term absentee Jurrien Timber.
