It hasn't taken him long - substitute Aleksandar Mitrovic goes straight into the referee's book.
Martin Olsson goes into the book for Norwich too.
All that from an off-the-ball-incident. They both lost their tempers. Things are getting rather heated!

Dwight Gayle pulled it down and hit it early, after a wonderful ball from Jonjo Shelvey.
Newcastle are right back in it!
Dwight Gayle
It's all go here... Seconds after going two goals down Dwight Gayle pops up to get his second of the game to ensure a barnstorming finish at St James' Park.
The pacey forward gets on the end of Shelvey's superb pass and fires past Michael McGovern.
Jacob Murphy
Surely it's all over now? Jacob Murphy picks the ball up 30-dd yards out, comes forward and blasts a shot which takes a deflection off Jamal Lascelles and loops over Karl Darlow.

Newcastle haven't created much in the last few minutes and you feel that Norwich will be happy to sit back and take the three points.
Graham Dorrans
Yellow card for delaying the taking of a Newcastle free kick.
Jonathan Howson
Foul on Ciaran Clark.

'Yellow army, yellow army' is all you can hear from the small band of Norwich fans who've made the long and tricky journey to the north east this evening.

It's a big 15 minutes for Newcastle now. This could well be one of their season-defining moments.

Dwight Gayle should have had a hat-trick. He missed two absolute sitters.
