Sunderland fullback Bardsley hails Westwood influence in Villa draw
"Keiren's save to deny Darren was world-class," Bardsley told safc.com.
"It's tough to change your keeper midway through a game but we did well.
"The injury to Simon is a real disappointment for him because he's been in really good form.
"Hopefully he'll recover well and get back as soon as possible."
