Irons fans have feared that the Gunners right back could have a clause in his loan deal allowing the north Londoners to recall him in emergency.
Bit ClaretandHugh has established that is not possible under Premier League rules.
A spokesman for the PL made it clear that no player on a year’s loan can be taken back to his parent club before the next transfer window.
He explained: “The rules state clearly that any player on a year’s loan deal can only return within a transfer window.
Jenkinson therefore is a Hammers player until January and in all likelihood until next summer.
