Pangai Jnr caught Gold Coast outside back Phillip Sami in the first half of the Broncos’ 34-12 win over the Titans on Saturday.
The lock was sin-binned for the incident and will also have to sit out the clash with the table-topping Storm.
“I wouldn’t have given it to him but I’m not the judiciary,” Broncos prop Matt Lodge said about the sanction.
“You’ve just got to cop it on the chin … I probably think a sin-bin and a penalty or something, that gives their team an advantage for the stuff up but missing a game doesn’t help us, doesn’t help the team.”
With Pangai Jnr ruled out, the Broncos will be hopeful veteran Matt Gillett can overcome a back niggle while young forward Tom Flegler will also return after missing the Titans win due to suspension.
Gillett will be named to play against the Storm but only completed half an hour of light duties at training on Monday and regularly clutched his back throughout.
“It’ll be tough but we’ve got a great player coming in,” winger Corey Oates said.
“Gillo’s had a few weeks off now, he should be fresh and ready to go and all the niggles are gone.
“I’m really confident Gillo’s going to come back and play a good game.”
Friday’s game looms as a big test of the Broncos’ finals credentials.
Wins over lowly Canterbury and the Titans have lifted the Broncos into the top eight but Oates knows the high-flying Storm will be a different challenge.
Melbourne have won 32 of 47 games against the Broncos and Oates acknowledged Craig Bellamy’s team will be doubly inspired after their golden-point loss to Manly last weekend.
“That’s going to bump them up a bit,” Oates said.
“They always turn up whenever they’ve got to play us, doesn’t matter whether it’s here or down there.
“This is the game they probably look forward to most years, they want to come down and flog us.
“We’ve got to be on our best game and we’re going to have to stand up and, I think, play our best game of the year as a team.”
Waerea-Hargreaves could take his case to the judiciary given he is not risking any extra time on the sidelines with a not-guilty plea.
He would have ordinarily been free to play but will be forced to miss a week because of his poor disciplinary history.
He copped an extra 60 per cent loading for three prior non-similar offences over the past two years.
Canterbury prop Dylan Napa was also charged with a grade-one dangerous contact offence for his late hit on Victor Radley in the same game but will be free to play this weekend with an early guilty plea.
