Reds manager David Bell said Sims (elbow) will be activated from the 10-day injured list ahead of Sunday's game against the Pirates, C. Trent Rosecrans of The Athletic reports.

Cincinnati will announce a corresponding transaction shortly before Sunday's 1:10 p.m. ET first pitch. After being sidelined since late June with a right elbow sprain, Sims checked out fine during a five-outing rehab assignment at Triple-A Louisville, giving up two earned runs on six hits and three walks across 4.2 innings. Prior to getting shut down with the injury, Sims had factored into the Reds' closing mix, but it's unclear if he'll immediately be thrust back into high-leverage spots out of the bullpen as he returns from the IL.
