That’s because the BBC were behind Sky Sports in their coverage.
Fans watching on iPlayer were left about eight seconds behind those viewing on Sky.
And that meant key moments in the Super Bowl could be spoiled by those seeing it earlier than those watching on the BBC.
One Twitter user said: “BBC is a good 10,seconds plus behind sky? #SuperBowl2019.”
Another added: “Well Im watching Superbowl in 1080p (streaming) at least 30 sec behind. If i got 4k id take 5 minutes behind!!”
The first half in the Super Bowl was dominated by defence with neither the Patriots or the Rams able to dominate the other.
The score was just 3-0 to the Pats with Tom Brady struggling to exert much of an influence.
The third quarter started with a horror injury to Patrick Chung.
The Patriots star left the field on his own but was wearing a protective sling on his arm after a serious challenge.
There are suggestions he has either broken or dislocated his arm.
BBC Sport presenter Mark Chapman said on the injury: “The replay is horrific, the replay is not good so we will not show the replay to you.”
But American coverage on NBC did show the incident.
He added: “They’re going to show the replay now on CBS, i’m not sure if we want to see it, it’s horrible.”
The Patriots are looking for redemption after losing in the Super Bowl to the Philadelphia Eagles last year.
Brady is eyeing his sixth Super Bowl victory.
