Evans, Gareth Barry, Jake Livermore and Boaz Myhill reportedly stole a taxi and drove it back to their hotel after a night out in Catalonia.
The players subsequently apologised, but Evans has also seen himself demoted. Barry was the only other member of the four to start Saturday's FA Cup match against Southampton.
"There was a problem in terms of selection because of the incident to go with my strongest team," Pardew said. "But I felt I needed to make a little bit of a statement about the events.
"The guys' professionalism, time-keeping and everything has been spot on. We've had this one crazy evening and it doesn't reflect the work and the professionalism we do as a staff and as players," he continued.
The 'Baggies' lost 2-1 to Southampton at the Hawthorns to exit the cup, but their focus will surely be on retaining their Premier League status. Despite being seven points from safety, Pardew insists he can lead them to safety.
"I'm an experienced manager," Pardew said. "I've experienced this situation times before. Once I have been relegated, at Charlton, but I've got out of this situation before at Newcastle and Crystal Palace and I'm determined to get out of this one as well."
