Okocha missed the draw with Boro after pulling up in training last Friday and now could also miss the clubs game with Aston Villa this coming weekend.
"I'm now injured and that is why I did not play my Premiership game last weekend. I do not know how long this injury will take to heal." he said
The Nigerian midfielder claims that it is better for him to allow recovery from the injury before returning to action, but in the short term his absence his sure to be a big blow for the club.
"There is no need for me to risk playing while I am injured."
