Hegarty out for up to three weeks

Sydney Roosters centre Shannon Hegarty will miss up to three weeks after suffering a sternum injury in yesterday's one-point loss to Penrith in the National Rugby League.

Coach Ricky Stuart is likely to shift Ryan Cross from wing to the centres and promote winger Lelea Paea to the starting side for Sunday's clash with Cronulla at Toyota Park.

Hooker Michael Crocker returns from suspension but utility Chris Flannery isn't expected back from a shoulder injury until round five against North Queensland.
