However, manager Mark Hughes has revealed that Benjani is now close to beginning to train with the first team squad once again.
"He's looking to step it up," Hughes told the club's official website.
His fitness levels are good, but we've kept him from strking a football because of the nature of his injury.
"Obviously that is an important step, but we can't just throw him in at the deep end or there is a likelihood it will re-occur.
"He's at the point where he is comfortable enough for us to edge him on.
"We'd like to think he will be back in a week or so. Then if he's comfortable striking a football without putting himself at risk, he is an option again."
