The Italian forward was substituted after 63 minutes on Saturday and replaced by Patrick Bamford after a relatively ineffectual display in which he found himself marked out of the game by Luton Town's defensive midfielders.
Gnonto struggled at Kenilworth Road, his first league start since the turn of the year, but could be handed a second chance by Farke, against a side in Middlesbrough who are depleted in defence and likely to play a more expansive game, allowing greater space for Gnonto to exploit.
Farke's olive branch is not expected to extend to Largie Ramazani whose application in recent substitute appearances has been lacking, according to the manager's exacting standards.
The German is expected to stick with Dan James, who found the net with a sumptuous strike at the weekend, and Manor Solomon, who is eight games without a goal or assist and squandered a good opportunity to win the game for Leeds late on against Luton.
Here is the starting lineup we expect to see at the Riverside Stadium.
1. GK: Karl Darlow
Solid is how Daniel Farke described Darlow's performance at Luton, which is the clearest indicator, if it was needed, that he'll be starting tonight. | Paul Harding Photo: Paul Harding
2. RB: Jayden Bogle
Needs to rediscover the sort of form which saw him score at Coventry City a few months ago. Remains a goal threat and has good link-up with Dan James, while the alternatives aren't moving the needle enough for Farke to consider changing things in this position. Photo: George Wood
3. CB: Joe Rodon
Farke's most heavily used outfield player, Rodon has played every minute of every league game this season except for September's defeat at home to Burnley in which he was taken off with four minutes left. Photo: George Wood
4. CB: Ethan Ampadu
More than likely the centre-back replacement for injured Pascal Struijk, Ampadu is reliable and has a decent partnership with Rodon. Certainly makes more sense than a half-fit Max Wober or out-of-match practice Josuha Guilavogui, Sam Byram or James Debayo. Photo: Paul Harding
5. LB: Junior Firpo
Accomplished on the left throughout this season and if Leeds' wingers aren't firing on all cylinders, has popped up with more than a handful of goals and assists when needed. Photo: Stu Forster
6. CM: Ilia Gruev
With Ampadu moving back to centre-half, that gives Farke the opportunity to recall Gruev to central midfield. He will mitigate Joe Rothwell's absence on set-piece duty but Leeds are, all of a sudden, light in the middle of the park again. | Getty Images
