As Zach Davies warmed up for the 4th inning of the Cubs-Nationals game Tuesday night, David Ross and the team’s trainers jogged out to chat with Anthony Rizzo.

The Cubs star first baseman had just grounded out to end the 3rd inning and was wincing a bit as he warmed up in the field.

He remained in the game through the defensive inning but was replaced by Kris Bryant the following frame.

The team later announced he was dealing with low back tightness and was removed as a precaution.

“He’s day to day,” Ross said after the 6-3 victory. “Slipped coming out of the box and kinda tweaked his back.”

Bryant had a more light-hearted injury update on his teammate:

“I told him, ‘get out of this game, I wanna play first. I wanna play everywhere,’” Bryant said. “But you don’t want to see him go out there and do anything stupid and really hurt himself. I just went down there and told him, ‘hey, I can play first for you. Please don’t do anything stupid. We need you for the long haul.’

“He’s had back trouble before but I talked to him and he’s in good spirits. He’s Rizz, so…”

Rizzo has a back issue pop up nearly every season. He sat out for a few days during summer camp last year with back tightness and missed 9 games early in 2018 with the same affliction.

Prior to departing, Rizzo was 0-for-2 at the plate and was charged with an error on a ball that deflected off his glove in that 4th inning.

After a bit of a slow start to the season, he has turned it on lately with 7 hits and 5 RBI in his previous 4 games.
