Millwall manager Neil Harris was sent off just before half-time

Millwall striker Tom Bradshaw scored with his first touch seconds after coming on as a substitute to earn his side a draw with Middlesbrough at the Riverside.

Bradshaw bundled home after Matt Smith had got on the end of a Ryan Leonard corner just six minutes after Paddy McNair had given Boro the lead.

The Northern Irishman slotted the ball past Bartosz Bialkowski in the Millwall goal after being slipped in by Ashley Fletcher following a superb team move.

Millwall will feel frustrated they did not take all three points after carving out the better chances, in a match which saw manager Neil Harris sent to the stands following an altercation with Middlesbrough first-team coach Leo Percovich on the stroke of half-time.

Brit Assombalonga headed straight at Bialkowksi and then came close to connecting with Fletcher's low cross with Boro on top early on, but Millwall were the more threatening side for the rest of the half.

Smith headed Murray Wallace's left-wing cross just wide while under pressure from Ryan Shotton, before Darren Randolph tipped over a Ben Thompson strike and Smith had a header cleared off the line by Adam Clayton from the resultant corner.

Thompson half-volleyed over the bar and Connor Mahoney's deflected strike narrowly missed the target as the Lions finished the half strongly, before manager Harris was sent off for a scuffle on the touchline.

Boro improved in the second half, with McNair posing a threat from midfield and Assombalonga having a penalty appeal turned down after his shot appeared to strike the arm of a Millwall defender.

The home side then took the lead when McNair swept in his first goal for the club, but Bradshaw's immediate impact brought Millwall deservedly level.

Middlesbrough were largely restricted to long-range efforts as they looked for a second consecutive victory, with Fletcher and Jonny Howson firing over from distance.

Millwall almost won it when Smith headed Mahoney's free-kick just wide in the closing stages, but Harris' side were forced to settle for a point.

Middlesbrough manager Jonathan Woodgate told BBC Tees:

"You want to win all of your games at home, but the first-half performance wasn't good enough. We didn't show up. I thought the second half was a lot better. The midfield three won the battle in the second half. We need to start putting 90 minutes together.

"We should have had two penalties from handballs in their box, which is very disappointing. They're blatant.

"Paddy McNair is going to get a lot more goals for us this season. He can break from deep and score goals, like an old fashioned throwback of a player who can get from box to box."

Millwall manager Neil Harris:

"We were so dominant in the first half that I was trying to hurry along with the game. He's got the ball under his arm, and I sort of wanted to hit the ball from under his arm. It wasn't aimed at the coaching staff, but he's moved and I've hit his arm.

"There's no issue there, and I was a little bit surprised I was sent to the stand for it considering there was never going to be an issue with Middlesbrough's coaching staff.

"I'm a little bit disappointed with that when I thought the fourth official might have had a little bit more of an input into various decisions on the pitch."
