Watch the Single Line Blues online guitar lesson by Ton van Bergeijk from Licks to Riffs Guidebook: Blues
This is a simple blues riff in C. There are many more alternatives, of course. The riff doesn't have to be note-for-note accurately. You'll have to adjust it to what is feasible, playable, and mainly to one's good taste. If you keep the same timing, you'll have plenty of leeway to avoid awkward fingering.
