Steele (back) will throw a bullpen session Saturday, Taylor McGregor of Marquee Sports Network reports.

Steele has been sidelined for nearly a month due to a back issue but has been throwing bullpen sessions for two weeks. Although it's encouraging that he's continued to throw off a mound recently, it's not yet clear whether the southpaw will be able to return to game action over the final week and a half of the regular season.
