Fabrizio Romano reported that the decision was made by the Ecuadorian FA and Arsenal, and Hincapie is returning to London for further assessments to confirm the exact nature of the issue.
Hincapie has become an important squad member since arriving from Bayer Leverkusen, making 33 appearances for Arsenal this season as the club navigates a busy schedule on multiple fronts.
The move keeps the 24-year-old at complex risk for Arsenal during a crucial run of fixtures, but the precautionary approach is intended to prevent a longer-term setback.
He is now on his way back to London Colney to undergo further tests, joining other Arsenal players who recently returned from international duty.
Hincapie’s versatility has been a valuable asset for Mikel Arteta, particularly given the depth required to compete across competitions, and his absence could shape Arsenal’s defensive plans in the near term.
This development follows recent withdrawals by William Saliba and Gabriel Magalhaes from international duties, with Bukayo Saka, Noni Madueke, and Declan Rice also among those who have left duty for the moment.
