In a multi-billion venue built for champions, the Los Angeles Rams have carried off the crown jewel: a Super Bowl trophy.

It took a precise 79-yard drive led by quarterback Matthew Stafford and capped by Cooper Kupp's 1-yard touchdown reception with one minute 25 seconds remaining for a 23-20 victory over the Cincinnati Bengals.

With the win, the Rams, whose only other NFL title came 22 years ago when they were based in St Louis, joined last year's Tampa Bay Buccaneers as the only teams to win a Super Bowl on their home field -- doing it in front of a sell-out crowd at the $A7 billion SoFi Stadium.

The winning drive, during which Kupp's 4-yard touchdown reception was negated by offsetting penalties, ended soon after with the NFL offensive player of the year easily beating Eli Apple in the right corner of the end zone for the winning score.

Star wide receiver Kupp had four receptions for 39 yards on the championship drive.

"Those guys just did a great job," Rams coach Sean McVay said. "They took over the game.

"So many contributions. It's about these players."

Even with that brilliant, decisive march to the Lombardi Trophy, it was LA's "fearsome fivesome" that made the difference.

Led by Aaron Donald and Von Miller, they sacked Joe Burrow a Super Bowl record-tying seven times, shutting down the Cincinnati offence after a 22-second spurt to start the second half gave the Bengals the lead.

Fittingly with time almost up, Burrow was under pressure from Donald on fourth-and-1 and threw an incomplete, setting off a football fiesta this city has not seen since the LA Raiders won the 1983 championship.

The 10 quick points at the outset of the third quarter put Cincinnati ahead for the first time.

Tee Higgins' 75-yard score made it 17-13 and was followed one play later by Chidobe Awuzie's pick.

Evan McPherson tied Adam Vinatieri's postseason record with his 14th field goal, a 38-yarder.

Higgins beat All-Pro cornerback Jalen Ramsey on the first play of the second half - the receiver clearly tugged Ramsey's face mask on the play.

After Matthew Stafford was intercepted on the next play, the Bengals got McPherson's field goal.

Then they tried to hold on as all of southwest Ohio held its breath.

But LA's relentless pass rush, led by its two biggest stars, Donald and Miller with two apiece, allowed nothing more.

Then came the decisive 15-play march, in which Kupp also converted a fourth down with a 7-yard run before his second touchdown of the game.

"It just comes down to this team and they way we prepared, they way we loved each other, trusted each other," Kupp said.

Kupp even earned the MVP honour despite often being double-teamed after fellow wideout Odell Beckham Jr went out with a knee injury in the second period.

Bengals head coach Zac Taylor said he was frustrated to lose knowing his team had an opportunity to tie or take the lead near the end.

"We were moving the ball. We were going to try to go win it," Taylor said.

"(To work) for the last six months, play 21 games, then you lose the Super Bowl - it's not a lot of fun."

Jarryd Hayne could be freed from prison as he awaits a third trial, with the former NRL star to apply for bail after a NSW court quashed his rape convictions upon appeal.

The 33-year-old has spent nine months behind bars, after he was found guilty of two charges of sexual assault without consent of a woman in her NSW Hunter bedroom on the night of the 2018 NRL grand final.

The ex-Parramatta player faced a retrial after his first ended with a hung jury.

He was jailed in May for five years and nine months with a non-parole period of three years and eight months.

But after his barrister Tim Game SC successfully argued two appeal grounds, the NSW Court of Criminal Appeal on Monday ordered another trial and quashed his convictions.

Hayne will now apply for bail at a hearing listed at Sydney's Downing Centre District Court at 10am on Tuesday.

His barrister Tim Game SC successfully argued the jury was given "profoundly wrong" legal directions, saying Justice Helen Syme's directions of law were "flawed in almost every possible way".

Prosecutor Brett Hatfield had previously admitted the language could have been tighter, but said "perfection is not required".

Mr Game also succeeded in convincing the appeal court it was an error to overrule a verdict from the first trial in relation to evidence he said explained the complainant's "abiding interest in having sex with Jarryd Hayne".

Another two appeal grounds were dismissed.

Mr Game had argued an outburst from the woman in the first trial, in which she yelled "no means no" under cross-examination, being played before his second jury was "highly prejudicial".

He also argued the jury's verdict was unreasonable.

The Crown contended in both trials that Hayne had left his friend's bucks party to meet up with the woman and forcibly performed oral and digital sexual intercourse on her, causing her to bleed from her genitalia.

A woman has been charged with the murder of a two-year-old boy in central Queensland last month.

The 22-year-old was charged after an investigation into the child's death following an incident at a home in Frenchville, a suburb of Rockhampton, on January 18.

Police say the boy was "known" to the woman.

Emergency services rushed the toddler to Rockhampton Hospital before he was transferred to the Queensland Children's Hospital in Brisbane, where he died a day later.

The woman has been charged with one count of murder and was due to appear in the Rockhampton Magistrates Court on Monday.

Jailed former NRL star Jarryd Hayne's sexual assault convictions have been quashed and a third trial has been ordered.

The 33-year-old was found guilty of two charges of sexual assault without consent of a woman in her NSW Hunter bedroom on the night of the 2018 NRL grand final.

The ex-Parramatta player faced a retrial after his first ended with a hung jury.

He was jailed in May for five years and nine months with a non-parole period of three years and eight months.

The NSW Court of Criminal Appeal on Monday ordered another trial, after quashing his convictions.

His barrister Tim Game SC put forward four appeal grounds including contending the jury was given "profoundly wrong" legal directions.

Justice Helen Syme's directions of law were "flawed in almost every possible way", he argued.

While prosecutor Brett Hatfield admitted the language could have been tighter, he said "perfection is not required".

Another ground was the overruling of evidence admitted into the first trial, which Mr Game said explained the complainant's state of mind in her "abiding interest in having sex with Jarryd Hayne".

He also disputed a "highly prejudicial" outburst from the woman in the first trial when she yelled "no means no" under cross-examination, played before his second jury and likely to bring about a "very sympathetic response".

But the Crown argued the woman appeared very deflated and flat directly after this exchange, and her monotone responses would be incongruent without viewing the preceding moments.

Both trials were told Hayne had left his friend's bucks party to meet up with the woman and forcibly performed oral and digital sexual intercourse on her.

"I do not accept the offender did not know or did not hear the victim telling him she did not want to have sex with him," Judge Syme said.

Chief Justice Tom Bathurst and Justices Helen Wilson and Ian Harrison are to publish the reasons for their appeal decision on Monday.
