After recovering from the hit, Staker spent the rest of the game on the bench in obvious distress and discomfort.
Hall will have to answer a charge of striking that is expected to keep him sidelined for an extended period of time given the severity of the report.
Sydney coach Paul Roos says the incident is out of character for Hall and admits that Hall will have to serve time for his on-field indisgression.
"It's pretty hard to justify anything like that. It'll go to the tribunal and he'll accept whatever penalty he's given," Roos said.
A remorseful Hall later says he regrets the incident.
"It was a spur-of-the-moment, split-second thing and it shouldn't have happened. It was a mind explosion. It looked really ordinary in the replay," Hall said.
"I'll cop that on the chin and whatever the tribunal comes up with, I've just got to cop.
"I'll take my medicine. Whatever they think is fair. It's pretty hard to defend my actions. It's there in black and white."
Hall's actions draws widespread criticism, most notably from Staker's parents who label Hall as a "weak mongrel" while former North Melbourne player Sam McFarlane, who was struck by Hall in a similar fashion 11 years ago, says that Hall has not learnt from his mistakes.
Rosemary Staker, Brent's mother, has urged the AFL to impose a season-long ban on Hall.
However, Amanda Hall, Barry's sister, defended her brother, saying, "He's a better role model for the kids than Ben Cousins. At least he's not a druggie."
Staker has ruled out pressing criminal charges or taking legal action against Hall.
Swans co-captain Leo Barry says that Hall let the team down.
"Everyone feels like he has let us down," Barry said.
"It is going to be something where he is going to have to earn the respect back from the playing group."
