Callan wasn't the only GWS player celebrating family news on Monday.
His teammate Sam Reid welcomed a baby boy on Monday with his wife Elissa.
The couple had been worried that their new addition would arrive on his due date - which also happened to be AFL Grand Final day.
Sam revealed on Monday that Elissa went into labour on Sunday afternoon and their son was born early Monday morning.
"What a start it was to what is going to be an amazing week. @elissareid__ you are frigen amazing," Sam posted to Instagram.
"🙌🏽🥰 she has delivered the most gorgeous little boy this morning at 3:38am and did it all natural as planned. My heart could not get any fuller for these two."
While the couple are yet to officially announce the name, from Sam's Instagram stories it looks like the new bub has been named Elijah.
Congratulations to all!
