Jones went on the DL on July 31 with inflammation in his throwing shoulder. In a side session on Friday, the right-handed reliever threw for the first time since hitting the shelf, and he threw again in the bullpen before Monday's game against the Blue Jays.
"Everything went fine," Jones said afterward. "Everything felt good."
Jones will play catch on Tuesday and throw another bullpen session on Wednesday. After that, he plans to return to the active roster on Friday, the first day he is eligible.
"I'm coming off [the DL] Friday, no matter what -- if I feel good, or I'm not going to get any better, depending on how you look at it," Jones said.
The 40-year-old's role remains a mystery. Jones was the Tigers' closer from 2006 through a blown save on July 25, when he was demoted in favor of setup man Fernando Rodney.
Rodney has displayed inconsistency and control problems, forcing the Tigers to adopt a three-man closing rotation, with Joel Zumaya and newly-added Kyle Farnsworth joining Rodney.
Tigers manager Jim Leyland wouldn't comment on whether Jones will become part of that rotation.
"No idea," Leyland said last weekend. "We'll just have to see how that plays out."
