The veteran receiver boosted his TD count for the season to half a dozen.
Hunter recorded his debut National Football League TD but it was merely a small comfort as the Rams overcame time zone issues to achieve a thirty-five to seven win over the Jacksonville at Wembley.
Los Angeles did not touch down in the Britain until the morning of Saturday - the prior day to the last fixture of this season's London games, which was the 43rd regular regular-season contest to be played in the English capital.
That was the last-minute any team has come for an league match in the UK, while the Jaguars, who also approached the game with a winning mark, had been present since Tuesday.
But the Rams charged into a 21-0 halftime advantage before sailing through the second half, with experienced wideout the Rams' star registering a three of scores as the team finished with five altogether.
Hunter made sure the Jacksonville evaded a scoreless game with the final quarter remaining, aiding to reduce the lead to 28-7, but it did not detract from an commanding victory by the visitors, who have been projected to be in title the race again this year having last secured the NFL's championship game in 2022.
