When the squads were announced for the friendly games against Walsall and Port Vale, Doyle's name was a garing admission from both sides.
Wolves officially announced the news on the clubs website in the early hours of this morning
Both Mick McCarthy and the clubs medical staff are hopeful of a quick return to training but to expect a return in two weeks seems slightly optimistic.
Steve Kemp the head of the medical team at Molineux said on the official site, www.wolves.co.uk, "The decision was taken to address it sooner rather than later and we are confident he should resume training within a couple of weeks."
