Poulter moved in with Crisp moved in not long after Collingwood selected him in the second round of the 2020 AFL Draft and was still living with Crisp and his family for months after his AFL career looked over when the Magpies delisted him last October.
Poulter subsequently earned a lifeline with the Western Bulldogs.
"It was almost like a proud dad moment (watching Poulter return) after seeing all the struggles that he was going through at home last year. To see him go through it was hard as a family," Crisp said.
"To see him pull through and see the light at the other end of the tunnel and get to work, then get the reward for work was a surreal moment. Now to have the opportunity to play against him just a few weeks in is pretty cool. Nonetheless, when you cross the white line, it's on."
