The centre tore a hamstring during last year's Six Nations win over Italy, causing him to miss five months of action, including his country's summer Tests.
However, he returned to help Western Province win the Currie Cup, scoring a brace of tries in the final and is now set to join Glasgow.
Before pitching up at the Warriors, he is expected to feature in the Tests against Samoa, New Zealand and Australia and after missing so much rugby, the 23-year-old is clearly champing at the bit.
Jones said: "(I'm) very excited. I not only missed the summer tour, I also missed the whole of Super Rugby as well.
"So I've missed a lot of rugby, and my focus on going into the Currie Cup was to get back to the form I had that time last year.
"I think I'm there or thereabouts and happy to be called up to the Scotland squad again."
