Canterbury hooker Michael Lichaa will miss four weeks with a knee injury.

The Bulldogs rake injured his knee in Friday night’s win over the Sea Eagles, however the month-long layoff will come as a relief to the 22-year-old who feared his season may be over.

Lichaa went under the knife on Wednesday and the Bulldogs have named former St George Illawarra No.9 Craig Garvey in his place for Thursday night’s match against Penrith.
