Oldham can confirm Harvey Makin has returned to parent club Wigan Warriors with immediate effect.
The prop forward made five appearances for the Roughyeds in 2026, three of them from the bench, and scored one try.
Head coach Alan Kilshaw said:
"Harvey has shown great potential during his spell with us and has been a pleasure to work with throughout his time at the club.
"He's applied himself well in training, taken on feedback, and continued to grow both on and off the field.
"Everyone here wishes him the very best in the next chapter of his career. We've no doubt he has a bright future ahead of him, and we'll be watching his progress."
