Newcastle Knights fullback Connor Watson has been ruled out of his side's clash with Canberra on Friday night.

The 22-year old failed to overcome a low-grade MCL injury suffered against Penrith last week and will not make the flight over to the nation's capital.

Knights coach Nathan Brown revealed that Brown was targeting a return to the field next week.

โ€œItโ€™s a minor MCL,โ€ Brown told the club website.

โ€œTheyโ€™re hopeful of him, reasonably confident for next week. Itโ€™s a short term one.โ€

Kurt Mann will take Watson's place in the side, and Brown was confident in his ability to get the job done.

โ€œKurtโ€™s actually spent some time there in the pre-season,โ€ Brown said.

โ€œItโ€™s not really new to Kurt.

โ€œHe fits in there easily.โ€
