Falkirk 0-4 Rangers
Jermain Defoe is unable to gather a cross from Leon King into the six-yard box, but it breaks to Cedric Itten.
However, the Rangers striker's shot is beaten away off the chest of goalkeeper Peter Morrison at the front post.
Falkirk 0-4 Rangers
Falkirk's turn to make a change, with forward Robbie Leitch replacing midfielder Charlie Telfer.
Falkirk 0-4 Rangers
Another double change for Rangers as they give players game time.
Captain James Tavernier and midfielder Bongani Zungu make way and it's a debut for 16-year-old defender Leon King, while forward Greg Stewart is given a rare outing this season.
Falkirk 0-4 Rangers
Another chance for Blair Alston, but the midfielder fires straight into the defensive wall.
Aidan Connolly wriggles clear from a couple of challenges and sets up Morgaro Gomis just outside the penalty box, but the midfielder's low drive trickles wide.
Falkirk 0-4 Rangers
Another shot on target for Falkirk.
It's Blair Alston again, but there is no repeat of his goal against Rangers when Falkirk beat the Glasgow side on their last visit in 2016 as his shot is held by goalkeeper Jon McLaughlin.
Falkirk 0-4 Rangers
Falkirk's management team have obviously realised the writing is on the wall and rest two of their key players ahead of return to league business.
Striker Conor Sammon and winger Callumn Morrison are replaced with Anton Dowds and Aidan Connolly, the midfielder who kind of lost his way after bursting on to the scene as a teenager with Dundee United.
Falkirk 0-4 Rangers
Rangers defender Calvin Bassey is the latest to go into the referee's book for kicking the ball away after conceding a foul.
It comes minutes after Falkirk centre-half Ben Hall also earned a yellow card.
Falkirk 0-4 Rangers
Rangers manager Steven Gerrard takes the opportunity to hand 18-year-old midfielder Cieran Dickson his debut, while winger Glenn Middleton is given his first appearance of the season.
Scott Arfield and left-back Borna Barisic, the scorer of the third goal, earn a rest.

Quote MessageTavernier was a full 50-60 yards away from that play when it went out to the left-hand side and he just motored forward. It's a great ball by Barisic and a brilliant goal from Rangers
James Tavernier
Just when Falkirk were posing a bit of a threat, Rangers kill them off with a fourth goal.
Borna Barisic picks out opposite full-back James Tavernier with a precision cross to the back post and the Englishman volleys it expertly into the far corner from 10 yards.
Falkirk 0-3 Rangers
Another chance for Falkirk, but Blair Alston's shot is straight at goalkeeper Jon McLaughlin.

Quote MessageConor Sammon just kicked a bottle of water away in frustration. Rangers were late back on to the pitch and I think Calvin Bassey's concentration was still in the dressing-room
Falkirk 0-3 Rangers
So close to an ideal start to the second half.
Calvin Bassey is short with his back-pass to Jon McLaughlin and the goalkeeper's clearance is blocked by Conor Sammon.
However, McLaughlin is fortunate as it gets trapped under his arm and he is able to clear.
Falkirk 0-3 Rangers
And away we go for the second half.
A long, surely impossible, way back for Falkirk if they are to repeat Ross County's giant killing from earlier.
HT: Falkirk 0-3 Rangers
The 3-0 scoreline might not raise any eyebrows, but it shows where Rangers are at the moment considering they are able to make so many changes and ease aside a side full of top-flight experience.
Falkirk are not just League One leaders but that division's big spenders and have a team full of players who have recent experience in the Premiership.
Striker Conor Sammon is a Republic of Ireland international, Morgaro Gomis has played for Senegal, while fellow midfielder Blair Alston until recently was with Hamilton Academical. Indeed, Alston scored the last time Rangers were at Falkirk Stadium, when the home side won 3-2 back in 2016.
FT: Celtic 0-2 Ross County
There is a heavy police presence at Celtic Park, where a number of fans are outside the ground calling for Neil Lennon's dismissal as manager after that shock 2-0 home defeat by Ross County earlier.

Image source, SNSRangers are well on their way to filling that final place in the League Cup quarter-finals.
An early fine finish from Jermain Defoe set the tone, with centre-half Calvin Bassey, his first for Rangers, from close range and a trademark Borna Barisic free-kick have Steven Gerrard's side in a commanding position.
No way back surely for the League One leaders against their Premiership counterparts.

A couple of half chances for Falkirk and Callumn Morrison's cross is cut out well by Connor Goldson with Conor Sammon waiting to turn the ball home.

Quote MessageThat's a terrific finish. I'm not sure about the goalkeeper's starting position. You don't give someone with the quality of Barisic that amount of the goal to aim at
Borna Barisic
Definitely game over now.
We all know how good Borna Barisic is from these free-kicks and, when goalkeeper Peter Morrison gives him a bit too much of a gap to aim for behind the defensive wall, the Croatia left-back finds the inviting target with aplomb.
