Hafner turned in one of his best performances of the season in Sunday's 10-8 loss to the Tigers, going 3-for-5 with a home run and three RBIs. It was Hafner's first three-RBI game since May 16 against the Mariners, and only his third of the season.
"He had a good game [Sunday], but his back is sore again today," Indians manager Manny Acta said Monday. "We'll give him the day off in order to have him for [Tuesday]."
Acta said Hafner has been working with a chiropractor, but team trainer Lonnie Soloff doesn't believe Hafner needs anything more than that. Hafner, who had knee surgery May 31 and missed more than a month, has played in only 60 games this season.
