That's based on Roy Hodgson's latest decision to call up Tottenham Hotspur right back Kyle Walker to his latest England squad as a replacement for the injured John Stones, as confirmed by the FA's official website.
Walker has not played for England since the 1-1 draw in Italy in March and joins Spurs teammate Andros Townsend in earning a recall to the national side.
The decision comes as a real slap in the face for Jenkinson who now faces the reality that, in Hodgson's eyes at least, he is not even England's fifth choice right back.
That is despite playing a starring role for West Ham all of last season and turning in a man of the match performance at Sunderland on Saturday where he also scored a fine goal.
He has represented England Under 17s and Under 21s and earned a senior cap while playing for the Gunners, but Jenkinson was recently demoted back to the Under 21s and finds himself behind Nathaniel Clyne, Walker, Callum Chambers and even centre backs who can also operate at right back like Stones, Chris Smailing and Phil Jones.
Difficult to take
The decision is made all the more difficult to take for Jenkinson as England have already qualified for the Euro 2016 tournament in France after winning all eight of their matches so far and take on Estonia and Lithuania in dead rubber games.
But while many might see it as the perfect time to experiment and give players like Jenkinson – who was clocked as the fastest player in the Premier League last season – a chance to show what they can do, Hodgson clearly has his favourite clubs.
It will not come as a shock in East London, though. Players, staff and fans at West Ham are long since used to the fact Hodgson seemingly does not pick West Ham players for the national side.
West Ham and England have always enjoyed a special relationship. Indeed whenever England play away matches, West Ham fans have historically made up a large section of the support.
Hammers fans' patience has been well and truly tested by Hodgson, though, who since taking over has been reluctant to include players plying their trade in the famous claret and blue.
The 68-year-old has been in charge since 2012 and since that time has only ever called up two players from West Ham - Andy Carroll and Stewart Downing.
He has again ignored West Ham's core of Englishmen this season with not a single call-up between them despite Slaven Bilic's side impressing everyone with their fantastic start to the season that sees them sitting in sixth place after eight games.
On loan Gunner is England goner
Why Jenkinson has been ignored by England since making his debut is something of a mystery and must surely be making the player regret choosing to represent the Three Lions over Finland, the country of his mother.
He is a classy defender who gets up and down like a wing-back and offers superb supply to the strikers from the flank and playing week in, week out.
And it is not as if Jenkinson has been loaned out by Arsenal because Arsene Wenger does not rate him. The club offered him a new long-term deal which he signed before rejoining the Hammers on loan for a second season.
But it looks like he and his Hammers teammates still have it all to do to prove to the England boss they can cut it at international level.
