The 22-year-old attacking midfielder started the encounter at the Bet Butler Stadium and played for 85 minutes.
The Newcastle United-owned youngster played an important role in Rangers’ 3-1 victory, scoring the third goal for the Gers in the 52nd minute.
Following the comeback win for Rangers, manager McCall spoke highly of Slovenia international Vuckic.
"We had to move him on to the left today so we could get a bit more from Walsh on the right,” the Scot told Rangers’ official website.
“I know Haris prefers being on the other side so he can cut in and do what he did, but we gave him a bit of freedom to go and get involved in the game.
“He ended up being on the right hand side, and once he cut inside it was a fantastic finish. It’s pleasing for him to be playing a key part because he brings goals to the team.”
Vuckic joined Rangers on loan from Premier League outfit Newcastle in the January transfer window until the end of the season.
The attacker has not always played the entire 90 minutes, but he has established himself as an important player for the Glasgow outfit.
Rangers are currently second in the Scottish Championship table with 65 points from 34 matches, four points clear of Hibernian, who are third and have a game in hand.
