I'm Gonna Skate 'Til I Can't Anymore

Nyjah Huston isn't going to let his recent injury scare him into early retirement -- the skateboarding superstar tells TMZ Sports he plans to go all-out until he literally can't anymore ... just like Tony Hawk!!

The 28-year-old busted his ACL, partially tore his meniscus and fractured his tibia off a bad skating accident last year ... which kept him on the sidelines for months.

We spoke with Nyjah -- who's inching back to full recovery -- about how he handled the first major injury of his career ... and he said he couldn't wait to get back on his board again.
