Wolves defender Ronald Zubar expects to be fit for the start of preseason.
The versatile defender saw his 2010/11 campaign cut short by a back problem, with the complaint forcing him under the knife back in March.
"I'm getting better day by day and week by week," Zubar told the Birmingham Mail.
"I had to rest for a month after the surgery and then came back and started doing gym work to get the back stronger.
"I've started with (fitness coach) Tony Daley outside and that's never easy - we are never happy to see Tony!
"You know you are in for a hard day but I am happy to be back outside as staying in the gym is always difficult.
"I'll come back a little bit early before the rest of the lads just to check everything is all okay and make sure I am ready for pre-season."
