Bournemouth defender Tyrone Mings has suffered a back injury.
The setback will sideline him for at least another month.
Mings has missed Bournemouth's past two games, victories over Brighton in both the Premier League and Carabao Cup.
Cherries boss Eddie Howe said: "We thought it would be manageable with treatment, unfortunately he'll be out for a period of time."
Mings, 24, who joined the club in 2015, signed a new four-year deal with the Cherries at the start of the month.
