"I need to know when we're playing so I can organise training," he told the Western Mail. "For instance, if we're playing on Saturday then we'll have to train the following Monday.
"I want the Football League to let me know, in writing, at the close of business on Friday what the dates are.
"When I drive out of Crewe I want to know who I'm playing and when I'm playing. In my heart I don't think we'll be playing on the original dates - but I want to know in writing. The information we're getting at this club tells us that the matches will be played on Saturday and Tuesday."
"Television is running the game today, along with the police. It's a disgrace that we don't know what the dates are.
"It amazes me that fans are buying tickets without knowing when the games will be played."
Lennie is unlikely to get his wish, the football league are adamant they will not announce the exact dates until the teams involved know who they are playing.
Cardiff can of course be playing QPR, Oldham or Bristol City, all will depend on tomorrows games.
Tickets for City's home play off semi final are on sale with the ticket being valid for whenever the game is played.
