From BBC Sport:
Manchester City manager Mark Hughes says he expects newly-signed striker Roque Santa Cruz to be out of action until the end of August.
The 27-year-old joined from Blackburn for a reported £18m with City aware that he needed knee surgery.
"We knew he'd have a period of rehab when we signed him, but we have good options up front," Hughes told the club's website.
"Rather than bring him back too soon I'd give him the time he needs."
