Lennie may prefer to wait until later in the week before completing the paperwork so making Mahon available for the Wigan game at Ninian Park. It would also allow time for the player to meet and train with his new team mates ahead of the weekends action at Huddersfield.
Lennie told the Echo this morning
"Alan Mahon is joining us for three months and will link up with us at the team hotel before tomorrow's Second Division match at Port Vale. He could be among the substitutes, but I won't make a final decision until tomorrow."
The deal was in some doubt over the weekend. Lennie, Blackburn and the player had all agreed on the move but the players agent was getting involved and threatening the move. It's thought that Mahon has chosen City ahead of Division 1 clubs Coventry and Burnley.
Lennie had put out an ultimatum that he wanted the deal sorted today, the move could then become a full time one depending on the success of the loan period.
"Mahon was always going to join us, but his agent wanted to play the field. We wanted, we needed, a decision today and that has now been made. I won't bring in anybody on loan unless there is a chance we will sign them at the end of it."
Graham Souness, the Blakburn manager said
"We are happy for him to join Cardiff City. They were always the favourites."
