Belt exited Saturday's game against the Cardinals due to neck stiffness, John Shea of the San Francisco Chronicle reports.
Belt exited the game in the eighth inning after a swing. It's unclear how serious the injury is at this time, so he should be considered day-to-day. Belt was activated from the COVID-19 injured list prior to Saturday's game, and he went 0-for-1 with three walks and two runs scored prior to his exit.
