Lopez (groin) has rejoined the team and is expected to be activated from the 15-day injured list within the next few days, Meghan Montemurro of the Chicago Tribune reports.
Lopez will be eligible to be activated beginning Wednesday, so it appears he'll miss only the minimum after suffering a right groin strain. The right-hander put together a stellar month of August (0.87 ERA, 0.77 WHIP, 17 strikeouts and two saves over 10.1 innings) before getting rocked for four runs on four hits in his lone September outing prior to landing on the IL. Lopez should be in the mix for save chances upon his return along with Porter Hodge, who blew a save Saturday against the Rockies.
