Manchester United defender Phil Jones will be out for a minimum of three weeks, the club have confirmed.
Jones has mild thrombosis and will not be involved until the beginning of September at the earliest. The Manchester United man was omitted from the match day squad to face Tottenham earlier this afternoon.
United won that game 1-0 thanks to a Kyle Walker own goal, although debutant Sergio Romero had to make several smart stops towards the end as Spurs put the United rearguard under pressure.
With Jones a confirmed absentee for the next few weeks, it will reopen the question as to whether Louis van Gaal will dip back into the transfer market for centre-back cover.
Jones has not been the most reliable performer, suffering from a number of niggling injuries since his move from Blackburn, and Manchester United were heavily linked with a move for Sergio Ramos not too long ago.
That now looks dead in the water despite Real Madrid's continued pursuit of United keeper David De Gea so van Gaal will need to explore other targets if he wants reinforcements.
Is Blind the solution?
The game against Tottenham today did little to bolster the case for Daley Blind's continued inclusion in the middle of defence.
The Dutchman was caught out several times and did not look comfortable out of his preferred position. He remains an excellent and versatile option for van Gaal but if United want to be challenging on several fronts, they will need a stronger option to partner Chris Smalling.
Thrombosis can be the clotting of blood in the circulatory system, a potentially serious problem although Manchester United describe Jones's diagnosis as mild. Hopefully that's the case and we see Jones back on the pitch sooner rather than later.
What do you think Manchester United fans - should van Gaal strengthen in defence in the wake of this news?
