Lazio striker Miroslav Klose faces up to eight weeks out with a knee injury, the club have confirmed.
The Germany international has scored 10 goals in Serie A this season but was replaced at half-time during Sunday's 3-2 defeat to Genoa and, after visiting German specialist Professor Hans-Wilhelm Muller-Wohlfahrt, has been advised the injury will mean a lengthy lay-off.
A statement on the club website read: "This morning Miroslav Klose was visited by Prof. Muller Wohlfahrt in Germany, his own doctor, who diagnosed a severe lesion of the external collateral ligament in his right knee.
"The player will return to Italy either tomorrow or on Wednesday and start the protocol prescribed by the German specialist. The estimated recovery time is about seven to eight weeks."
Gills goalkeeper Stuart Nelson looked like he was going to earn his side a point with a string of fine saves but moments after wasting a glorious chance McClure showed exquisite skill to turn past Matt Fish and fire home.
Martin Allen's side would have gone top with a win but despite the efforts of Deon Burton they struggled to create chances, instead it was Wycombe who offered the greater threat, Sam Wood's fizzed half-volley their best chance of the first half.
After the break the visitors dominated with Nelson denying Jo Kuffour from close range and keeping out Dean Morgan when clean through.
But after firing wide when in a great position two minutes earlier, McClure made no mistake to earn his side all three points.
The game ended in disappointing scenes as a Gillingham fan came on and clashed with Chairboys goalkeeper Jordan Archer in the final seconds.
