Manager Kevin Cash said he hopes McClanahan will be "okay" after receiving treatment on his back Thursday, Marc Topkin of the Tampa Bay Times reports.
McClanahan was pulled in the fourth inning of Thursday's game against the Royals with mid-back tightness. After the contest, Cash noted that the issue lingered from McClanahan's prior outing but didn't provide any additional detail as to whether he may require a stint on the injured list.
