The SANFL will travel to Perth to take on the WAFL this Saturday, with McLennan part of the final 23 after being named in the extended squad earlier this week.
The Magpies skipper has recorded some impressive individual stats to start the season, averaging 23.4 disposals and 10.2 marks from his first five games.
He was named in the squad for the SANFL v VFL state clash last month, just missing out on final team selection.
This will be the third consecutive year McLennan has represented his state, with the 25-year-old earning the Fos Williams Medal twice in 2024, awarded to the best on ground for SA.
Saturday’s game begins at 4:40pm local time at Leederville Oval in Perth.
