Manchester United will be without captain Roy Keane for four weeks after he damaged a hamstring in last night’s2-1 victory over Leeds United.

Keane was not the only casualty of last night’s win. Juan Sebastian Veron wasanother to limp off, the Argentinian complaining of a sore ankle, while defender Mikael Silvestre, and midfielder, Quinton Fortune also picked up minor knocks. However it is Keane’s injury that will most concern United boss Alex Ferguson.

“Seba (Veron) and Roy Keane have got sore ones,” Ferguson said afterwards.

“Roy has got a hamstring injury. The intention was to bring him off five minutes after half time but he wouldn’t come off – typical Roy.”

Ferguson said United had “a lot of limpingbodies out there” against Leeds following Sunday’s Worthington Cup final defeat by Liverpool.

Keane has already missed three and a half months of the season due to hip surgery and his latest injury will keep him oujt of forthcoming PremierLeague matches against Aston Villa and Fulham.

United will want both Keane and Veron to be fit for a vital period at the startof April when they play Liverpool, Newcastle United and Arsenal, and the first leg of their Champions league quarter-final, in the space of 11 days.
