Lichaa out for four weeks

Michael Lichaa's scans are back and the Bulldogs club have confirmed the young dummy-half will miss four weeks.

The Canterbury No. 9 injured his knee in his side's 28-6 victory over the Sea Eagles last Friday and underwent surgery yesterday.

His side takes on Penrith tonight at the foot of the mountains where former Dragons hooker Craig Garvey will deputise for Lichaa.
