Sebastian Kris is unlikely to feature in the Raiders' finals campaign after he was sent off for a dangerous throw on Sione Katoa.
The winger's act cost the Raiders dearly with the Sharks only leading 10-6 with 20 minutes remaining. Cronulla went on to win 24-6.
Kris made the tackle after Katoa leaped high to take a catch in the air when contesting with Jack Wighton.
