MILWAUKEE (AP) – The Chicago Cubs are concerned about a possible COVID-19 outbreak after two coaches tested positive for the virus and three relievers were placed on the COVID-19-related injured list.

The team announced the positive test for bullpen coach Chris Young on Monday, with first base coach Craig Driver already away from the team following his positive test.

Relievers Brandon Workman, Jason Adam and Dan Winkler were placed on the COVID-19-related injured list. There was no word on whether their designation was the result of a positive test or contact tracing.

Despite the issues, manager David Ross said Monday night’s series opener at Milwaukee isn’t in jeopardy of being postponed.

“Everyone has tested today that is here and is negative,” he said.

Left-handers Justin Steele and Brad Wieck were recalled from the team’s alternate site in South Bend, Indiana. Veteran reliever Pedro Strop was selected as a replacement player from the alternate site. All three players were expected to be available against the Brewers.

Ross said the team is being “extra cautious” right now.

“I think that once you get a positive and what we got with Craig, it’s just on your radar for a while,” he said. “There’s always that underlying ‘How big is this?’ There’s concern, for sure.”

Ross also said the organization is hoping for the best and planning for the worst. The Cubs avoided any COVID-19 scares last season on their way to the NL Central title.
