Answer: If you're referring to the jurors, no. We see the entirety of their deliberations. If you're referring to the prosecution or defense, that is unknown. Given, however, that none of the jurors brought up the question, it's likely there was at least a check of his clothes to verify he had a hole in his pocket.
Given how easy it would be to simply tear a hole as an excuse, even if it was there, it wouldn't be much in the way of corroboration.
