The Canaries' chief substituted the influential winger with around 20 minutes of Saturday's game at Old Trafford remaining and replaced him with Elliott Bennett.
However, Hughton moved to allay fears that the former Leeds United man had suffered an injury problem, claiming he just wanted to shake things up.
He said on the club's website: "I just wanted to bring on some fresh legs to give us that spring.
"That was with the two up front I just wanted to freshen things up because it's always a tough shift you have to put out at Old Trafford - You know United are going to have a fair chunk of possession."
Hughton has called on his players to focus on the home game against Southampton next weekend as they require eight points from 10 matches to reach the magic 40-point safety barrier.
"We dust ourselves down," he added. "There have been times this season that we have been really good. It was always going to be a tough one here and we have to respect where we are."
