As the simmering feud between Pearson, Australia's most high-profile athlete, and Hollingsworth boiled over in Glasgow, Athletics Australia (AA) were forced to step in and sanction the coach.
Hollingsworth released a statement on Wednesday, labelling Pearson a "bad example" for the Australian team, after she failed to attend a pre-Games training camp.
"Sally was coming all along [to the camp] until the last minute when she opted to take a race in London," Hollingsworth said in his statement.
"What's lost here is she's the team captain and there's a reasonable expectation she'd be in the camp ahead of something as major as the Commonwealth Games.
"Her no-show sets a bad example to the entire national team."
The timing of the statement irked Athletics Australia, with Pearson set to compete in the 100m hurdles heats on Thursday.
Hollingsworth's statement included further digs at the hurdles specialist, who he said was unhappy due to his "challenging style".
The rift between Pearson and Hollingsworth began after the latter criticised the Olympic champion for her second-placed finish at the World Indoor Athletics Championships in Poland in March.
"Some time has past (sic) since Sally's camp has released its version of events publicly, and there's been some adverse reaction so I've decided the facts of the matter need to be addressed," the statement continued.
"I asked legitimate questions of her after the race [in Poland], and she didn't like the line I was taking. So via her agent she sorted a meeting with Athletics Australia's president, CEO and High Performance Director, which I was not aware of until the day of, or day before the meeting.
"While I thought at the time it was curious that I wasn't involved in that process in any form, Sally raised her issues, and the powers-that-be found no problems with my actions, and there was no case to answer.
"Subsequently Sally dug her heels in, as is her right, and asked for what is a new 'athlete performance adviser' which is the conduit between the athletes and Athletics Australia.
"I am that person for the bulk of the high performance athletes, but not all, from a work-load point of view. So we re-assigned Sally, which is fine.
"We had a good working relationship for nearly a decade, but she decided my challenging style wasn't what she was looking for, which is her prerogative."
