Hull KR have released prop Tom Garratt from the remainder of his contract “by mutual agreement”.
The forward has not played since suffering a concussion in the Robins’ victory over Warrington Wolves at the beginning of April.
Garratt has continued to suffer long-term symptoms since and been unable to return to full training.
The 28-year-old, who only joined the club from Dewsbury Rams ahead of this season, has now left Craven Park after a total of six competitive appearances.
“Tom leaves with the best wishes of everyone at the club,” said Hull KR in a statement.
