Anyone suprised? Six men, including footballer El Hadji Diouf, were arrested after a nightclub brawl which left a man seriously hurt. The Doncaster Rovers striker is understood to be one of five men who were bailed until 23 May following the fight at a Manchester club. QPR's Anton Ferdinand is understood to have been interviewed under police caution but not arrested. A 33-year-old man is seriously ill but stable in hospital, said a Greater Manchester Police spokesman. The alleged incident took place at 03:40 BST on Sunday in the Circle Club and the injured man was found close to the Barton Arcade club. A GMP statement said: "Six men were arrested on suspicion of violent disorder, five of whom have been bailed until 23 May pending further police inquiries. "Another man has assisted the investigation, which is ongoing." Mr Diouf, 31, who appeared for Senegal in the 2002 World Cup and has previously played for Liverpool, Bolton and Blackburn, did not play in Doncaster's 4-3 defeat by Portsmouth on Saturday, which saw them relegated from the Championship. Mr Ferdinand, 27, who was a team-mate of Mr Diouf's at Sunderland and is the brother of Manchester United and England defender Rio Ferdinand, played in his club's 1-0 defeat at West Bromwich Albion on the same day.
