At this point, it appears that Alfredo Simon will start Saturday's game against the Boston Red Sox followed by Mitch Atkins in Sunday's series finale.
Orioles manager Buck Showalter didn't rule out another guy from the bullpen, like Brad Bergesen or Jason Berken, getting an opportunity, but he did say there are no plans to bring back Jeremy Guthrie on three days' rest to start Sunday.
Simon would take the spot of struggling right-hander Chris Jakubauskas.
In other news, Showalter said Cesar Izturis continues to progress and will go on a rehab assignment after the All-Star break.
