27/01/2018 15:00 v Notts County
The Swans booked their place in the draw for the fifth round of the FA Cup, but will face a replay against Notts County to progress after being held to a 1-1 stalemate at Meadow Lane.
Luciano Narsingh gave the Swans the lead on the stroke of half time, only for Jon Stead to grab an equaliser after the break for the League Two side.
Swans boss Carlos Carvalhal made eight changes to the side that beat Liverpool 1-0 on Monday night.
Kristoffer Nordfeldt got an opportunity between the sticks, while skipper Kyle Bartley took the place of Federico Fernandez - who required stitches on the bridge of his nose during the victory over the Reds - in defence.
Connor Roberts and Tom Carroll provided width down the flanks, while Sanches made his first appearance following injury since the win at Watford earlier this month.
Narsingh was handed another opportunity to impress as he supported the frontline partnership of Wilfried Bony and Tammy Abraham.
Notts County manager Kevin Nolan, whose side knocked out Championship Brentford 1-0 at Griffin Park in the third round thanks to a goal from Jon Stead, made five changes.
Included in the line-up was Swansea-born skipper Richard Duffy who spent two different spells at the Swans.
After an early long-range effort from Mike van der Hoorn, the hosts gave the Swans an eighth-minute scare when Elliott Hewitt just failed to connect with a dangerous cross that was driven across the face of goal.
The Swans were enjoying plenty of possession and were showing plenty of commitment, but were sloppy on the ball at times until the overlapping Connor Roberts drilled in a great cross which Duffy did well to put behind for a corner with 14 minutes gone.
Renato Sanches was the next to try his luck from 25 yards, but his shot skidded inches wide. It was virtually the last piece of the action for the unlucky Portuguese as he was forced to leave the field in the 32nd minute with a hamstring injury. He was replaced by Ki Sung-Yueng.
Swansea should have taken the lead in the 34th minute when Narsingh delivered a great cross onto the head of Bony. But the striker headed straight at goalkeeper Adam Collin from six yards.
They didn’t have to wait much longer though to make the breakthrough after a darting run from Ki set up Narsingh who drilled home a fine finish for his second goal of the season.
The Swans were given an early warning that they still had a game to win three minutes into the restart when Jorge Grant curled a 20-yard free-kick just wide after a deflection off the wall, before Duffy fired inches over with a fine strike.
The chances kept coming for the home side as Grant headed a great chance wide from 10 yards.
But the Magpies, with all the momentum, grabbed a deserved equaliser in the 62nd minute. Some terrible defending, with the Swans claiming the ball was out of play, allowed Shola Ameobi to lay a pass off to Grant and his low cross was tapped home by Stead.
The Swans finally settled and started to look for a second goal without troubling Collin in the home goal until substitute Jordan Ayew tried his luck from long range in the 80th minute which the keeper saved easily before Bony headed inches wide in the last minute.
Despite the fact that the Swans dominated possession in the final stages, they could not make the breakthrough.
