Phillies manager Rob Thomson said Hoffman didn't pitch in a simulated game Wednesday due to a stiff neck, Alex Coffey of The Philadelphia Inquirer reports.
Thomson said holding Hoffman back was precautionary, adding that he expects the reliever to be "fine" for Game 1 of the NLDS on Saturday. Hoffman will be a high-leverage reliever for the Phillies this postseason following a regular season which saw him collect a 2.17 ERA and 89:16 K:BB over 66.1 innings.
