'Toughest goodbye': Sport star breaks down in tragic Instagram post

Former NFL star Tim Tebow wiped away tears as he farewelled his dog ‘Bronco’ in a heartbreaking video posted on his social media account.

The former Broncos and Jets quarterback posted a video on Instagram Thursday of himself feeding his beloved dog, Bronco, his final meal.

Tebow could not hold back the tears as Bronco eats his final meal in his lap.

“One of the toughest goodbyes,” Tebow wrote.

“Wanted to make a special tribute to the sweetest boy ever - thank you for all the joy you brought and all the memories.”

The photos chronicle the duo’s last near-decade spent together.

Tebow later posted a picture of burial spot, which he wrote is located in a “special place.”

The former NFL-star is currently signed in the minor leagues with the New York Mets after making a career switch to baseball.
