It also leaves Newcastle stuck down in 19th place, six points adrift of Alex Neil's Norwich side in safety and staring another relegation in the face.
Although Benitez's side do have a game in hand, they must play four teams with lofty ambitions before the end of the season including Southampton, Manchester City, Liverpool and Tottenham Hotspur.
Meanwhile Norwich are on an upward curve after taking seven points from three games.
'That's why they're staring at the Championship'
And speaking in his role as a pundit on BBC's Match of the Day, Newcastle legend Shearer highlighted the crucial differences between the two sides as they each bid to preserve their Premier League status.
"They're (Norwich) up for it for 90 minutes rather than for 45 minutes like Newcastle were," Shearer told MOTD.
"Newcastle didn't start at all in the first half, couldn't get to grips with Norwich... they got one goal and should have had two or three in the first half.
"There's only Aston Villa that's conceded more goals than Newcastle and this is one of the reasons that they're staring at the Championship I'm afraid.
"To be fair to Norwich they keep on going.
"But for Newcastle to get themselves back in the game and then defend like they did, that's what they're staring at the Championship."
Fate in Norwich's hands
Norwich have a tricky run-in of their own with the likes of Arsenal and Manchester United still to play.
But they will feel their fate is in their own hands with another relegation six-pointer against Newcastle's North East rivals Sunderland to come and other winnable matches against Crystal Palace, Watford and Everton to play.
Given the Magpies have spent nearly £100 million this season under a former England manager and now former Real Madrid manager, it is difficult to deny Norwich deserve the rewards for their efforts on a much smaller budget.
