Middlesbrough earned their first Sky Bet Championship win at the Riverside Stadium since December by beating 10-man Norwich 3-1.

The Canaries started the game on top and took the lead through Ashley Barnes, but the evening quickly took a turn when Borja Sainz was sent off in the 30th minute.

Boro levelled through Marcus Forss and Emmanuel Latte Lath put them ahead just before half-time.

Lukas Engel added a third in the second half to wrap up victory as Norwich missed the chance to move into the play-off places.

Norwich dominated the opening stages and tested the Boro defence early on when Sainz unleashed a curling effort just around the post.

They nearly had the opener in the 13th minute when a great ball released Dimitris Giannoulis down the left and the full-back found Barnes, who had a first-time strike palmed behind by goalkeeper Seny Dieng.

The early pressure paid off as the visitors took the lead in the 17th minute when Gabriel Sara picked out Barnes on the break inbetween the Boro defence and although the striker stumbled to the floor on his first go, he was able to stick a leg out on the ground to roll the ball past Dieng.

Norwich were reduced to 10 men when Sainz was tackled by Jonny Howson and the winger was shown red after flicking a boot out at the Boro captain.

Boro soon took advantage of the extra player on their first real attack of the game when Forss levelled in the 37th minute. Engel fired the ball into the box for Latte Lath, but the subsequent clearance reached the Finnish forward, who stabbed home from close-range.

The hosts took the lead just six minutes later when Matt Clarke’s cross fell to an unmarked Latte Lath, who easily tucked the ball into the bottom left corner.

Boro continued to threaten early in the second half with some dangerous crosses from both flanks. Angus Gunn made a quick stop to deny Riley McGree’s effort from a tight angle before Howson curled the ball over the crossbar from a free-kick.

Michael Carrick’s side extended their lead out of nowhere in the 62nd minute as Luke Ayling’s pin-point cross from the right found Engel at the far post, who smashed the ball first time underneath the goalkeeper.

McGree then forced Gunn to make a great punch from his powerful strike and substitute Anfernee Dijksteel had a chance saved from close range.

Boro retained possession well in the final stages and nearly had a fourth, but Engel was denied by a quick clearance.

Michael Carrick admitted Middlesbrough’s bench made the difference after they came from a goal behind beat Millwall 3-1 at The Den in the Sky Bet Championship.

Carrick’s Boro were on a high after Tuesday’s 1-0 Carabao Cup semi-final first leg victory over Chelsea and rounded off an impressive week with victory over another London side.

Joe Bryan opened the scoring for the hosts before strikes from Lukas Engel, Isaiah Jones and substitute Marcus Forss turned things around.

Matt Crooks also came off the bench to have a positive impact in the second half.

Carrick said: “We knew it was going to be a challenge but we found our way the longer the game went, I’m delighted for the boys.

“We showed good spirit and quality and the bench made the difference for us, which we missed for a period of time.

“I thought the squad felt strong today and it can get stronger. We have a good group.

“Marcus (Forss) has worked hard for a period of time now and it’s a big goal for him and for us.”

Millwall struggled to replicate their dominant first half display and lost their way in the second 45.

Manager Joe Edwards highlighted his team’s injuries and agreed that Boro’s squad depth played a part on the day.

He added: “We felt that today (Boro’s depth). I’ve felt it in other games as well.

“I remember being stood down there when we were hanging on to a 1-0 lead against Norwich and when I saw the subs they were bringing on I thought ‘wow, that’s some impact and it will now get harder in the final 20 to 30 minutes.’

“That’s something I felt today.

“There’s a group of around seven of our players in their tracksuits today who are unable to play and that hurts us.”

Edwards struggled to hide his disappointment after the Lions failed to make it four successive league wins.

He said: “It’s disappointing. The goals they scored were soft and the bottom line is if you are playing a team at that level and dominate as much as we did in the first half an hour we needed to cash in and get that second goal.”

Middlesbrough conceded early but battled back strongly to win 3-1 win at Millwall in the Sky Bet Championship.

Michael Carrick’s Reds, who beat Premier League Chelsea in Tuesday’s Carabao Cup semi-final first leg, claimed another London scalp on Saturday.

Joe Bryan opened the scoring for the home side at The Den but goals from Lukas Engel, Isaiah Jones and Marcus Forss turned things around in favour of the Teessiders.

Millwall took a deserved 10th-minute lead, as the visitors cracked under early pressure.

Ryan Longman’s cross was cleared but only into the path of Bryan, who guided his effort into the bottom right corner from outside the box.

The Lions came close to doubling their lead five minutes later. Bryan turned creator and whipped a dangerous cross into the six-yard box, with centre-back Jake Cooper’s first-time effort clipping the bar.

Boro spent large parts of the first half on the back foot but they managed to break forward and equalise seven minutes before the interval.

Jones, whose positive form carried on after his impressive display against Chelsea, threaded a pass to Sam Greenwood. The on-loan Leeds player found the Engel with a low cross and the unmarked Dane levelled with a  close-range finish.

The visitors took the lead in the 58th minute after Bryan misjudged heading a high ball, with pacey former Tooting & Mitcham player Jones advancing and coolly finished past Matija Sarkic.

Millwall sought a way back into the game but failed to replicate their dominance of the early stages and played slow passes around the back, much to the frustration of animated manager Joe Edwards.

The visitors turned the screw and looked the most likely to score again.

Substitute Matt Crooks showed quick feet, turning his man in midfield before unleashing debutant Luke Ayling down the right.

The former Leeds right-back produced an excellent pass for Morgan Rogers,  who failed to connect properly.

However, the points were sealed in added time when Forss scored as the visitors moved into the top half.
