GLASGOW, April 25 (Reuters) - Rangers captain Barry Ferguson will be out for up to four months after an ankle operation, the club said on Tuesday.
The Scotland midfielder had reconstructive surgery on Monday, having played with the problem for several weeks.
'The surgeons gave me a rough estimate of 12 to 16 weeks that I won't be able to play,' Ferguson told the club's website.
'It's a long process, but I have been through it with my knee (injury) so I can handle it. I am just glad it has been done and I look forward to next season.'
Rangers also said they are to play Northern Ireland champions Linfield in Belfast in new manager Paul Le Guen's first match in charge on July 6. The Frenchman will replace Alex McLeish at the end of this season.
