DETROIT -- Jose Valverde continues to recover from a lower back strain he suffered in Chicago, and although he said he's feeling better, manager Jim Leyland ruled out the possibility of his return in Sunday's series finale against Pittsburgh.
"He's not pitching," Leyland said. "Day off tomorrow, hopefully [he'll be] ready to go Tuesday in Cleveland. Hopefully."
Valverde worked out on the field at Comerica Park on Saturday and played catch for the first time. He said after the game his back was still "a little tight," but that he wasn't nervous and would play catch again Sunday.
Austin Jackson hit in the cage off a tee Sunday morning and felt fine, he said Sunday afternoon, but when he tried running, he felt his abdominal strain tighten up. He'll rest it on Monday before getting treatment ahead of the team's flight to Cleveland.
Jackson said his injury continues to be a day-to-day situation, with no guarantee he'll be ready for Tuesday in Cleveland.
"It wasn't where I want it to be," Jackson said of his injury, "but I can feel it getting better. Hopefully it's [ready] in Cleveland."
