Fantastic update from Chris "Swaggy" Baker -- the ex-NFL player is up and walking around the hospital ... one week after suffering a "serious" stroke.
The former Washington defensive lineman posted video of his status just minutes ago ... showing him taking steps as he makes his way through the facility's hallway.
As we previously reported, the former Washington defensive lineman said he was lucky to be alive after experiencing a medical emergency last Friday ... with his mother revealing he was responding as if the stroke was minor, and was expected to make a full recovery -- calling his improvement a "miracle."
A number of fellow former NFL players were thrilled by Baker's update ... with Robert Griffin III, Carlos Dunlap, Glenn Dorsey and Bashaud Breeland showing love in the comment section.
Olympic medalist Kellie Wells Brinkley added ... "Yessir!!!!!!!!! Keep going bro! We are behind you!"
Earlier this week, Baker sent a message to his fans ... saying, "Tell Your love ones you love em" ... claiming "my life almost ended 2days ago."
"I can't believe I had a stroke but God not done with me yet."
Keep it up, Swaggy!!
