Chris Froome struggled with the injury during last weekend's world championship road race
Chris Froome has been ruled out of the one-day Classic Il Lombardia in Italy with a back injury.
The Tour de France winner is suffering from an inflammation of the sacroiliac joint, which is causing pain in his lower back.
He cited the problem as part of the reason why he pulled out of last week's world championship road race and has not yet fully recovered.
Froome said: "Sadly, I won't be able to compete at Il Lombardia on Sunday. I had some back pain at the world championships last weekend and it hasn't settled down as I had hoped."
Il Lombardia is the last of the season's five "Monuments" and is one of the most prestigious one-day races on the calendar.
Froome's withdrawal is a blow to his hopes of ending the season as the No 1-ranked rider in the world.
The 28-year-old Briton currently holds an 80-point lead at the top of the standings over Joaquim Rodriguez, but the Spaniard is favourite for victory at Il Lombardia.
