Zeljko Brkic pulled out during the warm-up and he was rushed in at the last minute.
"I never expected to play this game, but in the warm-up Brkic had a problem and the Coach decided to send me out," Scuffet told Sky Sport Italia.
"It was an incredible feeling, as a Friulano experiences marvellous sensations having this Udinese jersey on his back.
"Today's victory will help us to emerge from a dangerous position in the table, so we are calmer now.
"Dedication? I dedicate this game to my beloved Friuli region."
