Fabio was substituted due to injury 20 minutes into the 0-0 draw with Chelsea in the London derby at Loftus Road.
"Fabio has pulled his hamstring and will be out for a number of weeks," confirmed QPR boss Mark Hughes to the club's official website. "Which is a blow for us."
Steve Bruce's 3-5-2 formation worked wonders against Millwall as Hull City ran out 4-1 victors. Ben Amos kept goal with his usual confidence but was beaten by Darius Henderson's consolation header in the second half.
John Cofie received praise from strike-partner Nick Blackman despite being replaced on 52 minutes during Sheffield United's 1-1 draw with Bury. Cofie headed a Blackman cross wide in the first half as the pair continue to build up a relationship on the field. "John is a great player," Blackman told the Sheffield Star. "He is up-and-coming. He’s on Manchester United’s books so he’s going to be one hell of a player. It’s still early days but we are working hard."
Reece Brown's Coventry were beaten 2-0 at Tranmere - a result which could have a negative impact on caretaker boss Richard Shaw's hopes of taking the manager's job on a permanent basis. The versatile defender did not get off the bench at Prenton
