Sunderland's dreadful season took another turn for the worst after a shambolic defensive display saw them thrashed 5-2 at Ipswich Town.
Martyn Waghorn nodded the hosts into a sixth minute lead only for Billy Jones to equalise 10 minutes later.
It was all downhill from then on in though for Simon Grayson and his struggling Black Cats, Jordan Spence nodded home the second before Bersant Celina and David McGoldrick scored twice within five shocking second half minutes.
Sunderland were all at sea at the back and fell to another Championship defeat, despite Aiden McGeady's late consolation. Sub Grant Ward adding the icing on the cake for Town.
Sunderland now without a win since the second game of the season.
Grayson made a bold team selection with no less than five changes from the side beaten by Cardiff City at the weekend including Robbin Ruiter and Didier Ndong being axed.
Both were on the bench alongside Tyias Browning, George Honeyman and Lynden Gooch, with Jason Steele, Billy Jones, fit-again Callum McManaman, Aiden McGeady and Darron
Gibson all in from the start.
Jonny Williams, out through illness, hadn't travelled with the squad.
There was an injury scare for Bryan Oviedo pre-match after he did his own fitness work away from the main group but he was fit to start.
It took Sunderland less time than it did against Cardiff City to fall behind.
South Shields-born former Academy graduate Martyn Waghorn with a glancing header past Steele from a Joe Garner cross. The worst possible start.
Sunderland, to their credit, bounced back quickly. McGeady with a wonderful corner to the near post and Billy Jones was there to power home from six-yards just four minutes later.
Ipswich continued to put Sunderland under the cosh though, Cattermole clearing a Garner header off the line before Jordan Spence nodded home from a Waghorn corner in the 27th minute to put Ipswich Town 2-1 up.
It could and should have been far more by the half-time whistle, Mick McCarthy's side carving out the clearer openings.
Steele saved from Tom Adeyemi before Matthews spared his blushes by clearing off the line from a goal-bound Bersant Celina effort that had squirmed under Steele's body.
Sunderland had half chances through McManaman, who twice saw efforts saved by Bartosz Bialkowski but it was Town that dominated as the half drew to a close.
Sunderland were a shambles defensively, every time Ipswich crossed into the box they looked like scoring as they headed into the break deservedly leading 2-1.
The second half started in a similar fashion to the first with Cattermole seeing a brilliant header tipped over by Bialkowski before Garner flashed an effort wide of the left-hand post.
Sunderland were forced into a change five minutes into the second half, Wilson taken off with an injury with John O'Shea on to replace him.
The evening took a turn for the worse for Sunderland in the space of five second half minutes, Celina with a smart finish after a Waghorn backheel in the 55th minute after Sunderland had failed to clear their lines.
Then on the hourmark McGoldrick capitalised on more awful defending to prod home the ball to make it 4-1.
McGeady turned on the magic to make it 4-2 in the 65th minute.
The Republic of Ireland winger cutting inside from the left wing before curling the ball into the top right-hand corner, an unstoppable effort but surely no more than a consolation.
McGeady tried his best to spark Sunderland into life, his free-kick sailing just over the crossbar before sub Lynden Gooch saw a penalty appeal turned down, referee Tim Robinson not interested.
Billy Jones came within a whisker of poking home his second of the night as the game entered the final 10 minutes, the ball going agonisingly wide.
Sunderland, pressing hard late on, had left themselves far too much to do following a shambolic defensive display.
And Town sub Grant Ward made it 5-2 in the 88th minute, rounding Jason Steele before firing high into the net.
A shocking night for Sunderland AFC.
