Both sides had presentable opportunities in the opening stages but it was Coventry who grew stronger as the first half wore on, making it count when Mason-Clark netted for his fifth league goal of the season.
Their dominance was to be short-lived, however, with Dasilva sent off after hurtling into Welington with studs raised halfway up the Brazilian’s shin.
Southampton were immediately incentivised by the man advantage and looked to be on course for a comeback win when Wood connected with Adam Armstrong’s cross to head into the ground past Carl Rushworth in the 56th minute after Coventry had failed to clear their lines.
Despite taking expected control of proceedings thereafter, Tonda Eckert’s side struggled to create any clear-cut chances and any time they did get a sight of goal, they found Coventry goalkeeper Rushworth in fine form.
