A 25-minute rain break after just five overs sent the players from the field with England on five without loss, and West Indies made the breakthrough in the ninth over - about 20 minutes after the resumption - when Paul got left-hander Keaton Jennings to edge a drive to wicketkeeper Shane Dowrich for eight, off the first ball of his opening spell.
However, that is now under review with the ICC keen to stamp down on personal abuse on the field of play.

"It's Test cricket and he's an emotional guy trying to do everything he can to win a Test match".
"The guys understand the legacy of West Indies cricket and they want to continue to inspire the next generation of cricketers to play the game".
On a rare day of toil in the three-Test series, the hosts managed just four wickets on day three of the contest as England marched to 325 for four at the close, already 448 runs ahead.

Meanwhile, it was noticeable that the ground announcer at the Darren Sammy Stadium made a point of announcing that anybody abusing others on the grounds of race, religion, creed or colour would be ejected.

"It feels fantastic. All the hard times I've had with injury, and the self-doubt, today I feel like an England", said Wood.
What was said between the players?
Gabriel was given an on-field warning by the umpires about using abusive language.
Speaking after the end of the day's play Root, who scored his 16th Test century and finished 111 not out, suggested Gabriel "might regret" his comments but would not divulge details. The objective is to make sure we have pace.
