Both teams will be looking to return to winning ways in this one after respective defeats in their most recent outings.
Match preview
Hull City were simply no match for Premier League outfit Newcastle United as they fell to a 2-0 defeat in Saturday's meeting between the teams.
First-half goals from Alexander Isak and Jacob Murphy saw Tim Walter's men come away empty-handed from yet another outing.
It is now three straight defeats for The Tigers, who are also winless in their last six matches since the final week of April when they defeated Coventry City 3-2.
With just one warm-up fixture left after Tuesday's affair, the hosts are desperate to get themselves back on track before Championship action gets underway.
Hull have recorded just one win from 10 home matches leading up to this one and now go in search of a much-needed pick-me-up in front of their fans.
Fiorentina fell to a 2-1 defeat against Preston North End when the teams locked horns at Deepdale on Saturday afternoon.
Raffaele Palladino's men went behind to Liam Lindsay's opener but wasted no time in drawing level through Rolando Mandragora before Will Keane decided the game in the penultimate minute of the first half.
That brought an end to a four-game unbeaten streak for La Viola dating back to last season's Serie A finale against Atalanta.
Fresh off the back of a first away loss since early May, Tuesday's visitors will be aiming to avoid consecutive defeats on enemy territory.
