There's something about the combination of Melbourne and Brookvale Oval that doesn't agree with Manly back-rower Glenn Stewart after his Origin III hopes were left in tatters due to a knee injury in the Sea Eagles' 26-22 loss last night.

Stewart was carried from the field just before half-time in another epic contest between the bitter rivals, his left knee twisting awkwardly under the weight of Storm utility Rory Kostjasyn.

The initial diagnosis was a strained medial ligament and a layoff of between 2-4 weeks - leaving him little chance to play the Origin decider in Brisbane on July 4.

Manly coach Geoff Toovey said the club wouldn't know the seriousness of Glenn Stewart's injury until he undergoes scans today.

But it didn't take Toovey that long to evaluate his side's sloppy performance.

''We can't seem to get to push the boundaries as much as they do and they're good at it,'' Toovey said. ''We let in a couple of soft tries the first half, we were most probably the dominant side the first half and probably should have been 18-0 up.''

Storm coach Craig Bellamy could not have been happier with his side's resilience.

''The boys were probably a touch flat at half-time - we needed to lift ourselves up from that and to their credit they did,'' Bellamy said.

''I thought all except that last 10-15 minutes of the first half, that's probably as good a footy as we've played all year.''

It was Stewart's first game against the Storm at Brookvale since last year's spiteful encounter, when his scuffle with Adam Blair sparked a wild all-in brawl and cost him a three-match ban.

There were no fists thrown last night and it didn't detract from an enthralling contest between the two most dominant sides of recent years.

It was only settled when Cameron Smith edged the runaway ladder-leaders ahead by more than a converted try with a penalty goal nine minutes from time.

In a match punctuated by momentum swings, the Storm jumped out to an early 12-0 lead through tries to Todd Lowrie and Smith - the latter coming after a feeble attempted tackle by Anthony Watmough.

A controversial call by video referee Paul Simpkins sparked a turnaround in the home side's favour - 18 points in 12 minutes started when Daly Cherry-Evans was awarded a try after Simpkins ruled Ryan Hoffman had knocked the ball from his grasp as the Manly No.7 attempted to ground the ball.

Brett Stewart and Jorge Taufua added their names to the scoreboard for a 18-12 half-time lead, but given the ferocity of their comeback, Manly's surrendering of the lead was surprisingly meek.

It was all precision as Melbourne regained the lead when Matt Duffie flew highest to reel in Cooper Cronk's cross-field kick. AAP
