Bowen stood in at the post-match press conference as boss Mark Hughes had dashed off to scout a player somewhere in Europe.
"You're disappointed because you think you're going to come away with a point," he said of Walters' missed spot-kick.
"He's missed a couple in the past but he struck it well enough. I just thought the keeper made a good save.
"Jon Walters gives everything for this club, so nobody in the dressing room will do anything other than pick him up and get him ready for the next game."
