The Cubs placed Brewer on the 60-day injured list Sunday with a fractured left hand, Taylor McGregor of Marquee Sports Network reports.
The 31-year-old suffered the injury when he punched the dugout wall with his left (non-throwing) hand after being removed from Saturday's 7-0 loss. Brewer gave up three runs (one earned) over two-thirds of an inning, which capped a five-appearance stretch during which he allowed seven earned runs in five frames. He'll now be sidelined through at least early September.
