The Tigers had a bit of a good news/bad news day in regards to some currently injured players. Gargantuan catcher Grayson Greiner has reportedly suffered a setback in his recovery process, per Chris McCosky of the Detroit News . Sidelined with a lower back injury since June 13th, Greiner experienced a “flare up” in that region during a rehab game with High-A Lakeland. Apparently, subsequent tests have revealed a deeper issue: “They took a scan and saw something,” said Tigers skipper Ron Gardenhire. “Not a break, but a stress area, so they’ve immobilized it.” Greiner has been shut down from all baseball activities for the moment, so catching duties will continue to be split between John Hicks and Bobby Wilson , while a potential call-up of prospect Jake Rogers still looms in the offing.
