Jackett will be without thirteen key players when The Lions entertain Yeovil at The Den with Alan Dunne becoming the latest casualty in an already overcrowded treatment room and the situation is likely to get worse before it gets better with loanee Jamie O'Hara returning to Tottenham after tomorrow's game.
"No-one is likely to be back for this weekend, I would be very surprised if they were," Jackett told the club's official site. "Neil Harris is the only one who just might be, but the likes of Danny Senda, Richard Shaw, Danny Spiller and Dave Brammer may be another 10 days away.
"I am hopeful that is the case, but you can never rely on it. When you have players who have been out injured there has to be a period of training and stability so that when they are back, they stay back and are match fit."
As for O'Hara, Jackett hinted that there was a possibility that the player could return to the club during the January sales.
"I have only seen him in one game so far but I was not disappointed with what I saw. I would very much like to have him back in January if possible."
