Right fielder Jason Heyward remained out of the Cubs starting lineup Tuesday after two days of tests to determine the source of the shortness of breath and lightheadedness that took him out of Sunday’s game.
Tests on Tuesday morning, before the series opener against the Reds, came back clear, according to Cubs manager David Ross. Heyward took one last test Tuesday afternoon, and the Cubs had yet to receive those results when Ross addressed the media.
“I talked to him a little bit this morning,” Ross said. “Still feeling a little bit fatigued.”
Ross said he didn’t know what caused Heyward’s ailment and that the tests were designed to rule out a series of conditions.
No Cubs player has tested positive for COVID-19, Ross confirmed Monday. Heyward would have been subject to the team’s regular testing, plus any hospital protocols.
“I think the concern would be Jason continuing to feel not like himself and us not knowing what it is,” Ross said.
Cameron Maybin replaced Heyward in right field Sunday, in the fifth inning of a 7-3 loss to the Cardinals. Maybin has remained in that role since. He hit a double and scored a run in the Cubs’ 5-1 win against St. Louis on Monday.
