Arsenal defender Jurrien Timber is set to miss Tuesday's Carabao Cup tie against Ipswich but his expected omission is viewed as precautionary. The Netherlands international made his first appearance of the season following a long-term groin issue in the Premier League win over Sunderland on Saturday, coming on as a substitute for Ben White, who suffered a muscular injury in the first half. Manager Mikel Arteta is also set to rest other senior members of his squad against Ipswich.
