It's surely dependent on the player. When Stephens came back from his long term ankle injury he was rusty for a few games but soon found his form. I've faith the club won't rush him back but if he's playing against Reading he'll be pretty close.
If we're going to continue playing Knocky as a 'second striker' we are in desperate need of quality out wide with Skalak and Murphy pretty unconvincing. Will Solly be back for the Reading cup game? Anyone know?
