Canterbury skipper James Graham is expected to miss a month of NRL action because of the hamstring injury suffered in the win over St George-Illawarra last week.
Scans this week revealed the extent of the injury he picked up just 17 minutes into his first game back since injuring his knee against the Sydney Roosters in Round 10.
He was also suspended for four games earlier this season following their fiery Good Friday defeat to South Sydney in Round 5.
Graham isn’t expected to play again until the Round 18 match against Brisbane.
