Radebe: Injury blow (RossKinnaird/Allsport)

It was initially thought that Radebe - who underwent arthroscopic surgery on his right knee and has torn ligaments in his left - would not play again this campaign as Leeds chase Champions League glory.

The South Africa centre back underwent the surgery after his side's 2-0 victory at Sunderland's Stadium of Light - the game in which he ripped the ligaments.

He had played against the Wearsiders following a brief recovery from the problems in his right knee, sustained as Leeds lost 3-2 to Real Madrid at the Bernabeu, but had to have the operation soon afterwards.

Manager David O'Leary - whose side currently lie third in the Premiership - said on Friday morning: 'It's a blow to lose the Chief for the run in to the season.

'But nobody can underestimate his powers of recovery and the determination he will show to bounce back.'

But Radebe insisted: 'I am obviously very disappointed at the timing of the injury. The league run in and the Champions League games are critical to the club, but the boys have shown the strength in depth the gaffer has worked hard to build.

'I am always positive, and I would like to think I have an even chance of being available before the season is over.'

O'Leary has urged his side to reproduce the form they displayed in beating Deportivo La Coruna 3-0 to move to the verge of the Champions League semi-finals.

He said: 'That was fantastic. It was a great performance by the team and a magnificent night for all at the club, but we have to put that behind us now and maintain our impressive form in the Premier League.

'The ultimate goal is to grab a Champions League qualification place by finishing third. I still think that's a massive task for us with the ground we have had to make up.
