Fuld played in six games after suffering the concussion, and said the symptoms gradually got worse, as he experienced headaches, fogginess and sensitivity to light and sound. But he said those symptoms have started to subside.
"I definitely felt them leading up to today, but I felt like today I turned a corner," Fuld said. "It's been progressing all along, but today, in particular, the symptoms are really minimal."
Fuld added it was the first concussion he's ever suffered, and that it hasn't been easy to deal with for many reasons.
"I think it's tough on several levels," Fuld said. "It's tough that the rehab is to do absolutely nothing. Off the field you're not supposed to watch TV or read. So it's tough. And it's hard to predict, so you have to take it day by day and not look too far ahead."
The earliest date Fuld could return would be Thursday, but he said it's too early to predict when he'll be activated. He also said he'd be in favor of adding extra padding to the wall in center field, as Aaron Hicks suffered a concussion on a similar play in center field the night before Fuld suffered his concussion.
"I wouldn't mind that at all," Fuld said. "It's definitely harder than I anticipated it being. I've never heard an argument against making it softer, so I wouldn't be opposed to that at all."
