We're underway at Carrow Road.
The team news has been announced and we'll start with the home side.
Norwich have been up-and-down under Daniel Farke this season, although at present they're currently on the upswing. The Canaries are unbeaten in their last three matches in the Championship, including their 2-1 win over Millwall last time out. Norwich will have their work cut out for them this evening to advance to the fourth round of the competition.
Chelsea come into the contest off their 2-2 draw against Arsenal. Antonio Conte will have been frustrated that his side conceded a late leveller against the Gunners as Hector Bellerin scored at the death to rescue a point for Arsene Wenger's men. However, the Blues have lost only one of their last 15 games and appear to be over the issues that caused them to stumble out of the gate.
Good evening and welcome to the live commentary of the FA Cup third round clash between Norwich and Chelsea at Carrow Road.
Chelsea subs: Morata, Musonda, Clarke-Salter, Eduardo, Ampadu, Sterling, Hudson-Odoi.
Farke has made one change to his side that beat Milwall on New Year's Day. Christoph Zimmermann comes into the fold to replace Nelson Oliveira, with Norwich reverting to a 3-4-3 formation. James Maddison leads the line as part of a three-man attack with Josh Murphy and Alex Pritchard.
STAT ATTACK! Norwich have been eliminated in all four previous FA Cup ties against Chelsea, most recently in the fifth round in 2006/07.
Conte has made several changes to his side that drew with Arsenal last time out. Michy Batshuayi, Pedro and Willian lead a three-man attack, while Davide Zappacosta and Kenedy operate in the wing-back roles. Danny Drinkwater and Tiemoue Bakayoko start in the heart of the midfiled. The back three has experience and strength as Gary Cahill, David Luiz and Antonio Rudiger all start ahead of Willy Caballero, replacing Thibaut Courtois between the sticks.
STAT ATTACK! Chelsea have progressed from 20 of their last 21 FA Cup ties against non-Premier League sides, with the exception their 4-2 defeat to Bradford in January 2015.
STAT ATTACK! Norwich have not beaten Chelsea in a competitive fixture since December 1994. A run that stretches for 14 matches, including three matches in the FA Cup.
FLASHBACK! Chelsea beat Norwich 2-1 in their last contest at Carrow Road in the 2015/16 Premier League season. Goals from Kenedy and Diego Costa fired the Blues to victory, despite a second-half strike from Nathan Redmond.
HALF-TIME: NORWICH 0-0 CHELSEA
It's all square at the break between Norwich and Chelsea as both sides struggled in the final third. The Canaries had the best openings of the first period as Josh Murphy missed a couple of good opportunities after breaking into the left inside channel. Chelsea struggled to get out of first gear and Antonio Conte will be demanding an improvement after the interval.
FULL-TIME: NORWICH 0-0 CHELSEA
Thanks for joining our commentary this evening. Until next time, goodbye.
There will be replay at Stamford Bridge to decide the tie as neither team was able to find a breakthrough this evening. Chelsea will be disappointed with their effort as they failed to force Angus Gunn into a great deal of action, with Norwich limiting them to efforts from distance. The Canaries will take heart from their performance and will be fancying their chances in the replay to advance to the fourth round.
