Bunn stepped in to the Canaries vacancy in Wednesday night's 1-1 draw with Southampton following the thigh problem sustained by Ruddy, which will see him sidelined for three months, and Snodgrass was impressed with his performance.
"We'll miss John. What he brings to the team is clean sheets," he said.
"He was calm, composed and pulled off some good saves but I would like to wish John a speedy recovery because he is a great chap and great keeper. His return will only bolster the team."
