The controversial striker has not played for the Seasiders since November but the club surprisingly opted to take up the option on his contract over the summer and had hoped he would return for pre-season training on June 29.
Ranger was a no show, though, and had shown no willingness to resume his career with the Tangerines until pictures of his car being outside Bloomfield Road emerged on social media this week.
But the 24-year-old has now revealed McDonald told him to return to the capital when he attempted to come back to training and has called for the PFA to step in.
Writing on his official Instagram, the former Newcastle man wrote: “How can I report for training in Blackpool and get told to get in my car and drive back to london by the manager. Shambles. PFA PFA PFA PFA PFA PFA PLEASSEEEEE!!!”
Ranger has only played 14 games for Blackpool but the troubles which blighted him at the Magpies and Swindon continued on the Fylde Coast.
He ranted on social media after being left out of the squad by former boss Jose Riga then disappeared without then manager Lee Clark knowing his whereabouts.
The striker lamented his pay-as-you-play deal in an interview with a YouTube channel back in April, asking how he was supposed to “fill my fridge” when he was not playing.
