CHICAGO -- Cubs outfielder Jason Heyward was placed on the seven-day concussion disabled list, retroactive to Monday, after he was injured hitting the wall trying to catch William Fowler's walk-off home run in the 14th inning on Sunday in St. Louis.
A five-time Gold Glove winner, Heyward slammed into the wall in the right-field corner at Busch Stadium and hit his head trying to grab Fowler's ball. Cubs manager Joe Maddon said he did not plan on playing Heyward on Monday against Marlins lefty Jarlin Garcia and wanted to see how the outfielder felt Tuesday.
"He popped it on that fly ball the other day in St. Louis on the home run by Dexter," Maddon said. "I knew he was not feeling 100 percent. We just have to go through protocol and take our time with it."

Heyward was batting .227 in 29 games this season.
The Cubs recalled versatile infielder David Bote from Triple-A Iowa to take Heyward's spot on the roster. Also, left-hander Rob Zastryzny was recalled and righty Cory Mazzoni was optioned to Iowa a day after making his 2018 debut and pitching an inning of relief on Monday. The Cubs also recalled right-hander Jen-Ho Tseng from Iowa to start Tuesday night against the Marlins.
And separately, star infielder Javier Baez (right groin tightness) was held out of the lineup Tuesday as a precautionary measure, but he said he could pinch-hit.
While Heyward is out, Maddon said Kristopher Bryant could move from third base to right field to fill in.
