This is exactly why I am very against these players joining other leagues that they are NOT under contract with.
How bad is it?
I heard he is going to be out for "just" 3 weeks. Anyway, personally, I think this could be a blessing in desguise in terms of forcing Pau to sit and allow his body to re-charge and rest, keep fresh for the hard season that awaits him. Phil just loves to play him extensive minutes. I am not a trainer nor I want to declare that I have knowledge about this, but I just feel he should just eat healthy right now, rest up and re-start training by Oct. I heard of boxers not wanting to "overtrain". They wait like 12 weeks before the fight before they step on the gas so to speak.
