Hull City have confirmed that Danny Graham will be out of action for three weeks with a knee injury.
The 28-year-old striker, who is on a season-long deal from Sunderland, suffered the problem during Saturday's 2-1 defeat at Everton in the Premier League.
An official Hull City tweet read: "Danny Graham is set to be sidelined for around three weeks with the injury he suffered in Saturday's game at Everton.
"Although scans have revealed the striker escaped serious injury following a first-half challenge by Gareth Barry, severe bone bruising around the knee will keep the on-loan Sunderland man out of action until next month."
Graham has failed to score in eight appearance for Hull this season.
