Wrexham manager Phil Parkinson was shown a red card after the match following a heated clash exchange with Barnet goalkeeper Laurie Walker.
The National League match between Wrexham and Barnet ended 0-0 at the Hive, a pretty flat affair save a 51st-minute red card for Callum McFadzean.
The Wrexham player was given his marching orders for leaving his foot in on Barnet stopper Walker after the goalkeeper had come out to collect a loose ball in the box.
