Roosters reveal extent of Keary injury

Sydney Roosters medical staff have revealed five-eighth Luke Keary has suffered an MCL strain to his left leg, and could miss up to four weeks.

Keary left the field early in the second half, but has escaped serious injury, and will likely return to the Roosters' line-up before the finals commence.

Origin forward Dylan Napa missed the win against the Dragons as he continues to work his way back from an MCL injury of his own, although roosters.com.au have confirmed he is likely to be available for this weekend's clash with North Queensland.
