Striker Rory Patterson has joined Linfield on a one-year loan deal from Plymouth Argyle.
The Northern Ireland international previously played for Coleraine in the Irish Premiership, topping the scoring charts and collecting player of the year accolades before going to England.
He recently went on trial with Hearts but was not offered a contract.
Patterson has been in dispute with Plymouth over the deferral of wages and did not return for pre-season training.
He signed a pre-contract agreement with Glentoran while playing for Coleraine but moved to Plymouth in June last year before making an appearance for the East Belfast club.
The 26-year-old scored 41 goals during his season with the Bannsiders and converted a penalty while playing for Northern Ireland against Morocco in a friendly last year.
Patterson's arrival may be a timely one for the Blues as Peter Thompson could face a spell on the sidelines with a health problem and Gary Browne has also undergone surgery.
Jeffrey has indicated that he may be interested in securing a permanent move for Patterson if he performs well.
Meanwhile Patterson revealed that Glentoran had been offered his services but he was unable to agree financial terms with the East Belfast club.
