Think Pardew said it was hamstring but not serious, i would be having a serious look at our warms up before the game and what our players do during breaks in play as think thats Evans, Gibbs, HRK and now Sturridge all been injured with a hamstring injury of some level within the last couple of weeks.
As for Sturridge, this was always the risk with him, when he plays he is a top player and thats what you hope you get, the flipside you know he is likely to be crocked at any time and sort of sums our season up that we get the negative flipside!
