Port Adelaide coach Ken Hinkley has revealed that emerging defenderย Darcy Byrne-Jones will be dropped from the team this weekend after arriving late to training.

"Unfortunately we will have a couple of changes - Darcy Byrne-Jones was late for a training and Tom Jonas didnโ€™t get up after training today," Hinkley told reporters on Thursday.

The Power travel to the MCG to face Carlton on Saturday afternoon, and Hinkley said there was no other underlying reason for his omission.

"There is nothing more to the Byrne-Jones story, he was late itโ€™s that simple. You know I tell it how it is. We are trying to build really strong standards."

The 22-year old has had a productive season, averaging 18.8 disposals off the half backline.

Ex-Demon Jack Trengove will be handed his first game for the club after crossing over at the end of the 2017 season, while Jack Hombsch will come in for the injured Jonas.

"The good news story is that Jack Trengove will make his club debut for us this weekend," Hinkley said.

"Trengove gives us plenty of flexibility. Heโ€™s played a variety of roles in the Magpies which is exciting for us."

The Power coach was excited about the team's upcoming assignment at the AFL's home of football.

"We love going to the MCG, everyone does. Itโ€™s where all the big finals are played."
