From what ive seen..

[colinwhite]

and this is only based on observations of matches. I wreckon the injury situation looks like this:

Harrison Read - groin strain or pull   4-6 weeks
Bobby decadova Reid  -hamstring pull 3-6 weeks
Harry Arter _ calf strain or pull 6 weeks
TC stomach bug
Stephen Sessegnon-ditto
Kmac -same injury as before whatever that was
kamara - ankle sprain ,playing on pain killing injection /strapping   90 per cent no ligament damage-

There may be other knocks .Suspect Bryan is still feeling his back problemandMawson may still be having problems. both have slightly restricted movement.
I dont have any evidence of any of the above other than seeing incidents in matches and how the players move and my own experience in football working with players.
To his credit Parker refused point blank to use any injuries as an excuse. One thing is clear though and that he doesnt think the younger players are ready / good enough.
