Penrith fullback Michael Gordon had scans on his injured right knee on Saturday morning to determine whether his NRL season is over.

The dynamic 27-year-old, who starred in the Panthers' 33-10 thrashing of Brisbane on Friday night, suffered a suspected anterior cruciate ligament injury when he fell awkwardly in a tackle in the 70th minute against the Broncos.

Brisbane superstar Justin Hodges suffered a grade one tear to his right hamstring in the first half, which Broncos officials fear could rule him out for up to six weeks.

He appears certain to miss the first State of Origin clash on May 25, and is in severe doubt for the rest of the series, although Queensland and Brisbane skipper Darren Lockyer is in no doubt after pulling up fine with a minor neck strain.

Penrith centre Timana Tahu's season is also in doubt due to a suspected ruptured pectoral muscle in the match - he will have scans on Monday.

Gordon has been in stellar form in 2011 and looked to be playing himself into a Blues jersey before the injury ended his night.

Penrith officials brought forward the scans on his knee to Saturday morning in order to determine the extent of the injury before NSW coach Ricky Stuart names his squad for the opening Origin fixture on Sunday evening.

Gordon rocketed into contention with a five-star effort against competition heavyweights Brisbane.

With the match in the balance, Gordon single-handedly destroyed the Broncos in an electrifying 10 minute period where he backed up a Luke Walsh run to score under the posts before setting up tries for Brad Tighe and Tahu.

His involvement in Tighe's four-pointer was particularly special, with the damaging 27-year-old producing a brilliant tackle-busting kick return, beating four Brisbane would-be tacklers before sending Tighe away on a dash to the tryline.

Gordon was realistic when asked about his injury after the match, hoping for the best while admitting it could be season-ending.

"If it's as bad as they say I'll probably miss the rest of the season ... I'll just have fingers crossed," he said.

"Expect the worst but hope for the best."
