Star midfielder David Mundy says he got goose bumps hearing the cheer from the Freo crowd when he entered the game in Saturday's match against Brisbane at Patersons Stadium.

The 2010 Doig Medallist started the game as a sub but was called into action in the second quarter when young gun Nat Fyfe sustained a shoulder injury.

His impact was immediate and he finished with 13 disposals, four clearances and a goal in just over a half of football.

"The feeling I got from that proves how much I missed being out there," Mundy said about the crowd's reaction.

"I felt like I was running on a cloud early on."

Mundy said replacing Fyfe was not the way he wanted to make his return, but from a personal perspective, he was pleased with his performance.

"It was good," he said.

"I felt like I was able to have a bit of impact."

But he said there was plenty of room for improvement.

"I was still a little bit rusty," he said.

"There's a few things I'd like to iron out in the coming weeks and, hopefully, I get a bit better each week."

Senior coach Ross Lyon said in his post-match media conference that Mundy would shed the green vest in Friday night's clash with the St Kilda at Etihad Stadium - news sure to please the Freo on-baller.

"I put my hand up to play a full game against Brisbane," Mundy said.

"I felt really good out there today and I pulled up very well, so I'll be doing the same for next week's game."
