West Indies head coach Richard Pybus, speaking at close of play, told BBC Radio's Test Match Special: "Nothing has been reported to me but if a comment was made we'll review it and if it was untoward we'll be addressing it".
West Indies fast bowler Shannon Gabriel has been banned for the first four one-day internationals against England after being found guilty of "personal abuse" in the St Lucia Test, the International Cricket Council says.
Umpires Rod Tucker and Kumar Dharmasena spoke to Gabriel after the finish of the Test and he was charged with breaching Article 2.13 of the ICC's code of conduct.
There was no formal hearing with Jeff Crowe, the match referee, as Gabriel accepted the charge, following which he was given a four-match ban and fined 75% of his match fee. Do you like boys?'
The nature of the paceman's words is not known but Root was picked up on stump microphones telling Gabriel "don't use it as an insult".
Gabriel has extended an "unreserved apology" for his comments.
"Don't use it as an insult", he said. There's nothing wrong with being gay.' I then responded: "'I have no issues with that, but you should stop smiling at me'".
In the post-match conference, he refused to divulge any more details of the incident saying, "Sometimes people say things on the field that they might regret, but they should stay on the field".
Root addressed the matter after the day's play.
A second user said: "I know he's from the wrong side of the Pennines but this is wonderful of Joe Root. The battle was a good contest".
The quick bowler, who was expected to earn a recall for the later part of the five-match ODI series against England, will resultingly miss the first four matches of the forthcoming rubber, scheduled to commence next week in Barbados.
