Ryan Mason disappointed with 'ill-discipline' that proved costly as West Brom lose at Coventry
Ryan Mason described Jayson Molumby's dismissal as a moment of ill-discipline as Albion sacrificed a two-goal lead to lose 3-2 at Coventry.
Aune Heggebo's double had earned Mason's visitors a handy lead on half hour at the CBS Arena but the hosts, helped by Molumby's needless cautions, struck back.
The Irishman picked up a first-half yellow card for a bodycheck near Coventry's corner flag and lasted just four minutes into the second period before a cynical shirt pull in midfield saw him dismissed.
The Sky Blues had pulled one back before half-time but in a little over 10 minutes Frank Lampard's hosts went from 2-1 down to 3-2 up against 10 men.
Mason felt the red card had a "clear" effect on the outcome. The head coach said: "I've not seen the first one, obviously I see the second.
"I'll protect the players, I always will, it's my job and responsibility.
"But I think it was a lack of discipline in that moment which has given the ref a decision to make.
"It's certainly something we need to learn from and avoid happening again especially where it was on the pitch. Very disappointing."
