The tie is delicately poised after both teams could not be separated in a goalless stalemate in last weekend's first leg at Carrow Road.
Match preview
Tight affairs tend to be played out in the first leg of playoff ties, but there were hopes that both Leeds and Norwich, two attack-minded teams, would provide the Carrow Road faithful with an entertaining contest last Sunday.
However, both sides cancelled each other out and lacked the cutting edge required to take a valuable advantage into the second leg. Just 13 shots were registered in the entire match, which also had an xG of just 0.76; only four Championship fixtures have had fewer shots and a lower xG this season.
Daniel Farke would presumably have been the happier of the two managers to come away from Norfolk with a draw, considering that his Leeds side came up against a Norwich outfit that have not lost on home soil since November 5. The German will still have concerns about his team's recent form, though.
Indeed, the Whites enter Thursday's contest having won only one of their last seven matches and have failed to score in four of those, including two of their last three games at Elland Road.
Leeds have come out on top in their last two home meetings with Norwich, though, including a 1-0 win in January, so there is reason to be optimistic as they endeavour to reach an EFL playoff final for the fourth time and first time since the League One showpiece in 2007-08.
Norwich also find themselves in a difficult spell of form as they have only won two of their last eight matches since the beginning of April, failing to win any of their last four in the process. They have also come out on top in just four of their last 10 away fixtures.
A first-leg draw with Leeds on home soil was considered by some quarters of the Canaries fanbase as a disappointment, but manager David Wagner has insisted that they have not 'automatically handed an advantage' to the Whites, who will host the return fixture at Elland Road.
Norwich's recent head-to-head record with Leeds leaves little to be desired, as they have won just two of their last 12 meetings with the Whites across all competitions. Their most recent triumph was at Elland Road, though, in February 2019 under the tutelage of current Leeds boss Farke, who steered the Canaries to a 3-1 win in the Championship en route to winning the title.
In what is their third appearance in an EFL playoff, Norwich are seeking to reach the final at Wembley Stadium for the third time, having previously done so in 2002 and 2015. Success on Thursday would see the Canaries become only the sixth team to reach the final with a 100% record having won at least three playoff semi-finals.

Team News
Leeds defender Pascal Struijk has been ruled out for the rest of the season after undergoing groin surgery, while striker Patrick Bamford is facing a few weeks on the sidelines and will be a major doubt if the Whites make the playoff final, as he is nursing a "minor trauma to his patellar tendon".
Daniel James managed to shake off a costal cartilage injury and an oblique abdominal muscle tear to feature as a second-half substitute in the first leg, and the winger will be pushing to start on the right flank ahead of Wilfried Gnonto.
Farke could be tempted to name the same midfield trio of Archie Gray, Glen Kamara and Ilia Gruev, but one of those could make way for Joel Piroe to start in attack if the German boss opts to bolster his frontline that should also include Georginio Rutter and Crysencio Summerville.
As for Norwich, they are sweating over the fitness of striker Joshua Sargent who was forced off in the closing stages of the first leg with an ankle injury.
Ashley Barnes is also a doubt after missing the first leg with a calf problem, so the potential absence of him and Sargent could see forward Sydney van Hooijdonk handed his first start for the Canaries since joining the club on loan in January.
Both Liam Gibbs (muscle) and Onel Hernandez (broken foot) remain in the treatment room, but Jon Rowe was fit to start the first leg and the 12-goal winger is expected to retain his place on the right flank, supported in attack by Borja Sainz.
Leeds United possible starting lineup:
Meslier; Byram, Rodon, Ampadu, Firpo; Gray, Gruev, Kamara; Gnonto, Rutter, Summerville
Norwich City possible starting lineup:
Gunn; Stacey, Duffy, Gibson, Giannoulis; Nunez, McLean, Sara; Rowe, Van Hooijdonk, Sainz
We say: Leeds United 2-1 Norwich City (Leeds United to win 2-1 on aggregate)
Leeds will certainly fancy their chances of success in front of a fired-up Elland Road crowd and have already beaten Norwich on home soil this season, so they enter Thursday's contest as slight favourites.
The potential absence of top scorer Sargent would be a huge blow for the Canaries, and although they can rely on other star attackers to step up in the final third, they may just come up short against the Whites this time around.
