The Tigers faithful have grown frustrated with owner Assem Allan, and, with 19.04 on the clock - the year in which the club was formed - play was delayed as the home fans started throwing yellow stress balls onto the pitch and whistles were blown.
On the half-hour mark, they continued with whistles and chants of ‘we want Allam out’. And the first half ended in a drab stalemate.
However, ten minutes after the restart, Nigel Adkins’ men got the matchwinner through former Wolverhampton Wanderers forward. Dicko benefitted from a Jackson Irvine pass to blast past Sheffield goalkeeper Jamal Blackman.
The goal was the French-born Mali international’s fifth in the English second-tier league this season. And he was afforded 73 minutes on his 27th league appearance while Nigeria wing-back Ola Aina played the entire duration of the game.
In their next encounter, the KCOM Stadium outfit welcome Barnsley for a Championship tie on February 27.
They are placed 20th in the log after garnering 32 points from 33 games.
