Schalke midfielder Weston McKennie has been ruled out for six weeks after suffering a partial rupture to the medial collateral ligament in his right knee during his side's 1-1 draw with Hannover on Matchday 19, the Royal Blues confirmed on Monday.

The USA international came off the bench in the 63rd minute at the VELTINS Arena, replacing Bayern Munich-bound Leon Goretzka in central midfield. However, he only lasted 20 minutes on the field, as a clash of knees in a tackle with Hannover's Felix Klaus left the 19-year-old clutching his right knee.

He tried to continue after the original challenge and hobbled on for a few seconds, before going to ground again in obvious discomfort. After a brief examination on the pitch from the club's medical staff, the Texan was then escorted off for further treatment, with Benjamin Stambouli coming on in his stead.

McKennie, who is enjoying his breakthrough season as a senior player for club and country, is expected to miss Bundesliga games against Stuttgart, Werder Bremen, Bayern, Hoffenheim, Bayer Leverkusen and Hertha Berlin, as well as Schalke's DFB Cup quarter-final with Wolfsburg.

The Royal Blues currently occupy third place in the Bundesliga standings, but are without a win in their last seven matches.
