According to The Yorkshire Evening Post, Leeds defensive duo Liam Cooper and Stuart Dallas are out for around six weeks.
Centre-back Cooper has had surgery on a knee injury, while Dallas has fractured his foot. Both sustained these injuries in the win over Sheffield United recently.
What is now becoming clear is the huge lack of defenders The Whites have and how perilously close they are to a major injury crisis. Fellow right-back Luke Ayling and centre-back Gaetano Berardi are already out injured, and manager Marcelo Bielsa has had to turn to makeshift defenders and academy players.
In fact, Dallas, who was filling in for Ayling, was already a makeshift right-back, while Kalvin Phillips, who is primarily a midfielder, played as a centre-back at the weekend.
One thing that Leeds should possibly think of doing is looking at a short-term deal for a defender. Their current lack of players will be alarming for the Argentinian manager, particularly in such a busy period of the year. There are plenty of talented players that are currently free-agents such as Glen Johnson and Robert Huth.
It would be hugely disappointing for Leeds, who are currently second in the Championship, to let their season slip out of control as they go through this horrendous injury crisis. The club only really have one established centre-back available in Pontus Jansson and no right-back. Bielsa cannot afford to ignore this issue.
While this would be a brilliant chance for some of the younger players in the squad, this is an exceptional season for Leeds, and they do not want to chance their arm with their squad too often.
