Preston are set to offer short term deals to two of the three trialists who have been at Preston over the past few weeks. Sebastian Graz is a striker who was released by French club, St Etienne after being redeemed surplus to requirements. Preston are short of strikers after Hume's loan period expired. Brown is injured and King hasn't played for a good number of weeks. Graz will sign a short term deal which will see him go straight into the squad for the festive period. Lesjal is the other trialist who has been offered a deal to stay at Preston. The Czech keeper is to be used as back up with Wayne Henderson being told that he will never play professional football again due to ongoing back problems. Ferguson has Arestidou as his number two to Lonergan but is short of cover so Lesjal will come in handy.
