Northampton hooker Dylan Hartley will miss this weekend's Premiership match at London Irish after sustaining an injury against Wasps.
That was the word from Saints director of rugby Jim Mallinder who said Harltey has a hairline fracture of his eye socket.
The injury forced the England international off the field in Northampton's 24-6 win at Franklin's Gardens last Friday.
He was was replaced by Mike Haywood who is now set to start in Saturday's clash at the Madejski Stadium as Saints look to retain their unbeaten record in the Premiership.
"The swelling has gone down but Dylan has got a hairline fracture of his eye socket," said Mallinder told the Northampton Chronicle and Echo.
"It means he will be out short-term and he won't play this weekend."
