"We're not going to rush him or push him or anything," Marlins manager Mike Redmond said. "It's all going to rely on how he feels from day to day and how we progress. We're going to take it slow. There's no reason to rush him."
Redmond went on to applaud Major League Baseball's concussion protocol, mandatory steps that are taken in order to maintain player safety.
"[Concussions are] happening more frequently," said Redmond, who was a catcher for 13 years in the big leagues from 1998-2010. "I remember from the time I played there really wasn't anything. I think that's great, that it's obviously become a big issue and making sure that guys get onto the field when they're ready and well and healthy.
"These guys are in great hands. The doctors were evaluating immediately with Polanco. He was with the doctor, and they evaluate him and keep an eye on him and close tabs."
