"It's just one of those plays, two outs, you've got to try to make that play at all costs," Rizzo said. "[Russell] went all out, I went all out. Thankfully, we didn't hit our heads on each other. He kind of skidded a little there. We were both laying down, both asked each other if we were all right, and thankfully, we are."
The Cubs' athletic trainers and manager Joe Maddon checked on the pair, and after a few minutes, decided both could stay in the game.
"It was really awkward from the dugout," Maddon said. "[When you go see them] you just hope they're fine. You're running out there looking for blood -- there's no blood, nobody was howling in pain. Your first thing is, they're going to be fine and then you're looking for some kind of bleeder, and that was also good.
"I talked to Riz and he said, 'He hit me in the chest and I'm fine.' OK. Then we talked to Addy, and he was typically not highly talkative at the moment but he said, 'I'm fine' and we left."
Cubs starter Jake Arrieta watched as the two collided.
"It's a scary moment," Arrieta said. "They were both giving a lot of effort on that play. It's one of those unfortunate things where two guys are going all out to make.
