According to a report emanating from BBC Sport, Manchester United's Owen Hargreaves may have to stop playing football within the next two years.
The 28-year-old has been limited to just 37 first-team appearances since joining the Red Devils from Bayern Munich for £17 million in 2007 due to persistent knee injuries.
The versatile midfielder has had two operations to cure the tendinitis problems which he suffers in both knees, but he is apparently still experiencing pain.
It is claimed that the 42-time capped England international may not be fit in time for the beginning of the 2009/10 campaign.
Despite the fears, it is thought that Hargreaves is confident he will overcome his knee problems and make a full recovery.
However, it is also said that his situation is so delicate that he is monitored on a day-to-day basis, and that increasing the intensity of his rehabilitation programme may aggravate the problem, and possibly cause worse damage.
