Robbie strained the medial ligament in his left knee just minutes after netting the winner against Middlesbrough on Tuesday night and Martin Jol revealed a double-whammy on Thursday with the news that Jermaine Jenas' ankle injury will force him out for up to four weeks.
Martin reported on Friday afternoon: "Mido is back from injury and he looked well in training, so that's a good thing for us.
"Robbie will be out for up to six weeks with his knee but hopefully he'll be back earlier because he's someone who can heal quickly. JJ is out for four or five weeks, that's a blow for us after he just came back from injury.
"Hossam Ghaly's suspension is over and he's back in the squad but Didier Zokora is now suspended for three games and misses Saturday."
Anthony Gardner (knee) also misses out.
Mido has recovered from his groin injury and is back in the squad to face Charlton on Saturday - perfect timing with his fellow striker Robbie Keane facing up to six weeks out.
