Steven Davis and Craig Cathcart replace Daniel Ballard and debutant Ali McCann.
GOAL - Austria 1-1 Northern Ireland
Louis Schaub
Austria are level - although this one should be disallowed for offside.
Stefan Lainer lifts a cross into the box which Adrian Grbic deflects on with his back. Two defenders fail to clear it and substitute Louis Schaub smashes home with an acrobatic volley.
He was offside but the officials didn't see.

Josh Magennis even looked over to the linesman before shooting for that goal. A very unusual goal. Shocking defending by the Austrians.

GOAL - Austria 0-1 Northern Ireland
Josh Magennis
Scenes!
Austria think Josh Magennis is offside, but he's not - and he scores.
It's a good passing move by Northern Ireland and Gavin Whyte picks out Paddy McNair, who plays a first-time pass to Magennis.
To the naked eye he looks offside, but Andreas Ulmer is actually keeping him on. Three Austrian defenders look to the officials while Magennis smashes the ball past the keeper.

Conor Washington and Liam Boyce have put a great shift in for Northern Ireland and, with 62 minutes gone, they can clock off for the night.
Manager Ian Baraclough is keeping the shape, though, as he sends on Josh Magennis and Gavin Whyte to replace them up front.
It's a positive move from Baraclough, who is obviously happy that a front two is working well and occupying the Austrian defence.
Northern Ireland have continued their good work from the first half, but the back three will need to stay alert with the enigmatic Marko Arnautovic now on for the hosts.

It is a first save for Michael McGovern now as he's suddenly become a lot busier.
David Alaba's corner finds captain Julian Baumgartlinger, whose header is stopped by McGovern.

Northern Ireland keeper Michael McGovern hasn't actually had to make a save yet. Although he has attempted more passes (20) than any of his team-mates.

Scare for NI. Reinhold Ranftl gets a good head onto David Alaba's cross and it's a decent stop by the NI keeper. The flag goes up for offside, it wouldn't have counted.
SUBSTITUTION

Both sides make changes. Josh Magennis and Gavin Whyte replace front two Conor Washington and Liam Boyce for Northern Ireland.
Marko Arnautovic, who only arrived in Austria from China yesterday, replaces Michael Gregoritsch.

Bit fortunate for NI. They think Stuart Dallas has been fouled so stop playing for a second. Michael Gregoritsch tries to take advantage but his cross is blocked.
