'Workaholics' Star Blake Anderson -- Still Rehabbin' After Table Crash

Here's a shocker -- "Workaholics" star Blake Anderson says alcohol WAS a factor when he decided to jump off his roof onto a ping pong table last year ... fracturing his spine in the process.

In fact, 10 months after the injury -- which was all caught on tape -- Blake says he's almost fully healed ... but still needs a little physical therapy.

But he refuses to let the back pain keep him down, Blake tells us he's been soldiering through the pain so he could continue to work.
