The Warriors were hit with a double whammy at Mt Smart Stadium on Saturday night, going down 32-12 to the Manly Sea Eagles, while possibly losing Shaun Johnson for the season.

After being thrashed 24-0 to the Roosters last weekend, the Warriors desperately needed to get back on track against a Sea Eagles side that's been rocked by off-field dramas.

However, Andrew McFadden's side put in another lame performance and instead of looking to grab a spot in the top four, they're now in danger of missing out on the eight.

Those prospects will be further hampered if Johnson's injury is as bad as it looked and it has to be said that the life went out of the Warriors in this game once their star halfback had gone.

However, even with Johnson on the field, the Sea Eagles were able to inflict damage early.

Ligi Sao gave the Warriors fans a taste of what to expect once he joins the club next year, when in the eighth minute he was able to stay upright with three players trying to tackle him close to the line before offloading the ball to Jake Trbojevic, who had all the space he needed to score.

Steve Matai kicked the extras, but only lasted on the field until the 20th minute, having to come off after whacking the back of his head onto the ground when falling over. The Auckland-born centre went for a concussion test and didn't return.

Fifteen minutes before the break, Johnson made another of those wonderful solo runs to put the Warriors on the board, but this one had consequences as in the act of diving to ground the ball his left ankle became trapped in between a couple of Sea Eagles players and twisted badly.

Johnson was helped off the field and taken to hospital and there must be some doubt as to whether he'll play again this season.

His absence led to Tuimoala Lolohea coming into the halves, Raymond Faitala-Marriner moving to centre and Sione Lousi playing in the second row.

The Sea Eagles were rewarded for their hard work early in the second half when Jorge Taufua rounded Glen Fisiiahi on the left edge for their second try.

After that the points came thick and fast. In the 47th minute Brett Stewart seized on a loose ball under the Warriors' post to give Manly their next try.

Tuafua notched up his second try in the 53rd minute to pretty much wrap up the game, although that wasn't the end of the bad news for the Warriors as they were to lose Bodene Thompson with what appears to be a serious ankle injury.

When Stewart went in for his second try in the 68th minute, that was the signal for many of the 15,812 spectators to head for the exit gates - and you can't blame them.

They would have missed Albert Vete's maiden try in the 73rd minute and Matt Ballin scoring the Sea Eagles' sixth try four minutes later, but they probably wouldn't care.
