Danny Trejo was recently seen in a wheelchair making his way through a Canadian airport … but fans shouldn’t jump to conclusions!

Here’s the deal … Danny and his son Gilbert were spotted arriving at Toronto Pearson International Airport on Monday … and Danny, being pushed along, gave some observers cause for concern.

A source close to Danny tells TMZ … the beloved actor — known for his assorted badass characters — had a knee replacement … and at airports, a wheelchair makes it easier for him to get around. That’s it … Danny is fine.

The explanation is actually pretty important context … ’cause poor Danny has been the target of death hoxes in the past … the most recent happening last month!

As we reported … it all started when tributes started to circulate on Instagram … and the hoax really took off when John Leguizamo shared it.

The actors were both in “The Infiltrator” … so it stood to reason in the moment that JL might know if something had happened to Danny.
