The Eagles midfielder provided a compelling argument for mouthguards after his teeth were broken in a collision with Collingwood ruckman Jarrod Witts during the Pies' gripping eight-point win at the MCG on Saturday.
Yeo dropped a simple mark inside West Coast's forward 50m on the stroke of half-time and copped a double-blow from Witts' a split-second later.
Trainers searched for Yeo's teeth during the half-time break, but luckily the roots remained in his mouth and can be capped.
To his credit, Yeo soldiered on after half-time and earned coach Adam Simpson's respect.
"It was a big knock…he should have taken the mark. He kept on going, I don't know if he was in a hell of a lot of pain or not, but he didn't seem to take a backward step after it," Simpson said.
"We've been impressed with Elliot's role in the last few weeks," Simpson said.
"We've explored him through the midfield and we feel like it's added some flexibility and some size in there.
"And he's only going to grow from that, he's been doing it for two weeks."
After the match, a good-spirited Yeo tweeted: "All I want for Christmas is my two front teeth…"
