Hey look, rules in the Scottish League Constitution: http://www.scottishfootballleague.com/docs/009__034__constitution__rules__SFL_Constitution__Rules__1346425915.pdf
123.2.10 During the period of the temporary transfer, the player will not participate in
either the Scottish Football League Cup Competition, Scottish Football
League Challenge Competition or the Scottish Football Association
Challenge Cup Competition, without the prior written consent of the lending
club.
Where is the prior written consent from Liverpool? I want to see it.
Just kidding Jambos, you won!
