Sure if that's what it is. I'm not privy to the medical reports is all.It was only a kick on the knee ffs. That's a pain injury, but not necessarily a performance hurting one. Once the bruising heals a bit, if the mobility isn't affected then the only way that hurts him is if he takes another kick to the same spot.
I reckon he'll be fine for Tues,unless something tore or was chipped, which doesn't seem to be the case.
