The goalkeeper will walk away from Coventry on a free transfer at the end of the season after turning down a new deal to stay at the Ricoh Arena.
Boothroyd had his supporters rolling in the aisles as he compared an offer from Celtic for the keeper to being £3.50 and a bag of haggis.
Some friendly banter followed between Neil Lennon and Boothroyd but as reality sinks in at Coventry Boothroyd decided to drop the highly rated keeper from the Coventry side that lost 3-1 to Millwall on Saturday.
“As a manager, you’ve got to make decisions and I made one regarding the goalkeeper (Westwood),” Boothroyd admitted.
“We’ve got a situation where I want him to sign, his representatives want him to sign, the club and everybody in Coventry wants him to sign but he’s not quite sure yet.
“I do want to make it very, very clear that I absolutely love Keiren. I think he’s a terrific keeper and a brilliant lad.
“He needs fair but firm handling and I think he’ll go all the way to the very top. But he’s not ready, nobody’s come in for him and therefore I’ve got to go with what I think is consistent and settled.
“I want Keiren to play in the Premiership with us but, as good as he is, I’ve got a decision to make before the next game.
“I have to have a chat with him and find out it he’s part of the future here or not. If he isn’t, we’ll have to deal with it.”
This time next year Westwood is almost certain to be playing in the Premiership or SPL as Boothroyd cracks jokes for the dwindling crowds following Coventry.
