Lively (pectoral) will be activated from the 15-day injured list and start Sunday's game against the Brewers, Gordon Wittenmyer of The Cincinnati Enquirer reports.
Lively has been sidelined since June 24 by a pectoral strain, and he'll return to the mound without a rehab assignment. It's unclear how deep he may be able to work into the game as a result, though it has been only 17 days since he last took the mound.
