Aloiai was hit with a grade-two dangerous contact charge for running into Shaun Johnson on Saturday, after the Warriors halfback attempted a two-point field goal.
The contact was penalised by the bunker after the siren, allowing Johnson to kick the Warriors level at 22-22.
A golden-point stalemate meant the match ended in a rare draw.
Aloiai will miss Manly's trip to Gold Coast next weekend with an early guilty plea, while he would risk a second game on the sidelines if he fights the charge and loses.
Manly coach Anthony Seibold refused to delve into the incident when asked after the match.
"If I say it shouldn't have been a penalty I'll be called a whinger," Seibold said.
"If I say it should have been a penalty then potentially I'm not looking after the players in my group.
"It was adjudicated a penalty and we get on with it."
Cronulla winger Sione Katoa is the other player facing a ban out of Saturday's match, with a one-game suspension looming for his high hit on Cameron Murray.
If Katoa was to fight the charge and lose, his ban would double to two matches.
Cowboys pair Sam McIntyre and Kulikefu Finefeuiaki were both charged for dangerous contact during North Queensland's seven-point loss to Parramatta on Saturday, but can accept fines.
Eels second-rower Bryce Cartwright can take a fine for dangerous contact from the same match.
