The Cubs shook up their outfield depth chart Tuesday afternoon before the series with the Phillies kicked off.

Jason Heyward was placed on the 7-day concussion injured list (retroactive to Sept. 12) and outfielder Trayce Thompson was called up from Triple-A Iowa.

To clear room for Thompson on the 40-man roster, the Cubs moved Michael Hermosillo to the 60-day IL. (Hermosillo has been ruled out for the season with a left forearm injury, so the move to the 60-day IL is merely procedural).

Heyward was injured running the bases during Saturday’s game against the Giants. He was out of the lineup Sunday and under the evaluation of the Cubs training staff.

When asked how Heyward is feeling Tuesday afternoon, David Ross said:

“Not good,” the Cubs manager told Marquee Sports Network’s Taylor McGregor. “That’s one I’m sensitive to. Hits close to home for me. I’ve talked to him every day. He’s just still foggy and having some symptoms that definitely raise some concern but the doctors are on top of it.

“The nice thing about the 7-day concussion IL, it gives you a chance to get rid of some of that fogginess. If it’s nothing serious, you can be back pretty quick. And if it is serious, it gives us a chance to assess and then get him the right treatment that he needs.”

Ross dealt with concussions throughout his career and understands firsthand the effect head injuries can have on players.

Thompson, 30, is the brother of NBA star Klay Thompson. The Cubs purchased the outfielder from the Diamondbacks in May of this season.

He was originally drafted in the 2nd round in 2009 by the White Sox and he has notched 202 MLB games in his career. Thompson smacked 13 homers with a .738 OPS in 262 plate appearances with the Dodgers in 2016.

With Triple-A Iowa, Thompson has hit .233/.344/.492 (.835 OPS) with 21 homers and 63 RBI in 88 games.

Ross felt like the Cubs needed another right-handed bat off the bench and with Heyward out, Thompson also provides outfield depth. But rookie Alfonso Rivas figures to get most of the playing time in the outfield while Heyward returns to health.

Hermosillo will spend time at the Cubs complex in Arizona rehabbing and getting stronger for next season.

Also on the health front, Nico Hoerner appeared in a rehab game Sunday afternoon with Iowa. The Triple-A team was off Monday and the plan is for Hoerner to suit up Tuesday and Wednesday, take Thursday off and the organization will evaluate from there.
