Premier League - El-Hadji Diouf 'goes missing'
The Premier League side have flown off for a pre-season tour of Austria but there was no sign of the controversial Diouf on the plane.
Diouf spent the second half of last season on loan at Rangers but the Scottish giants declined to try and make the move permanent.
"We can’t find him. Nobody knows where he is," a club source is quoted as saying in the Daily Telegraph.
It is believed that Blackburn are keen to sell the former Liverpool and Bolton ace but they have yet to receive any firm bids and are now struggling to even contact the player they signed from Sunderland for a undisclosed fee back in January 2009.
Last season Diouf was sent out on loan soon after he was seen taunting Queen's Park Rangers player Jamie Mackie while he lay on the pitch with a broken leg during an FA Cup match.
After that game QPR manager Neil Warnock said of Diouf: "I was going to call him a sewer rat, but that might be insulting to sewer rats."
In 2004, he was embroiled in spitting incidents with a Middlesbrough supporter and the Portsmouth defender Arjan de Zeeuw, while he was also once investigated by police for allegedly making a racist comment to a white ball-boy.
