Bees icon Canos, 26, left England for a loan move to Olympiacos last month.
But the Spaniard was left heartbroken this week when his mother sadly passed away.
Canos is a fan favourite in west London after guiding Brentford to the big time in 2021.
And teammates were quick to pay tribute when Toney equalised for the Bees in Saturday’s Premier League clash with Arsenal.
The striker fired home with just 15 minutes remaining at the Emirates.
Toney celebrated his 14th goal of the season as he ran towards the Brentford bench.
And the star was then given a shirt by pals that bore the message “We’re all with you Sergi”, which he proudly displayed to the cameras and crowd.
