Arizona also tweeted a statement from Ray, who thanked fans for their support over the past 24 hours.
Arizona manager Torey Lovullo said Ray had symptoms of a concussion, but his cognitive testing and balance were good. Ray will remain with the Diamondbacks for the remainder of the road trip and be examined by the club's training staff and medical team on a daily basis.
"We saw Robbie today,'' Lovullo said. "He came into the clubhouse, and he looked really good. Obviously, the wound was repaired with a couple staples in his head. He just said he felt a little bit sore. So everything is trending towards a very positive outcome, and we're very thankful for that.''
Ray was struck squarely in the head in the second inning by a line drive off the bat of Luke Voit.
Lovullo said Ray never lost consciousness after he was felled by the line drive estimated at 108 mph. It was hit so hard that it stayed aloft, and third baseman Daniel Descalso caught the ball in the air in foul territory for an out.
Ray's teammates quickly ran to his side. He was helped up and then driven off the field on a cart for an examination.
Ray was enjoying his best season in the majors, with a 9-5 record and a 3.11 ERA for Arizona, which entered Saturday leading the NL wild-card race.
In a corresponding roster move Saturday, the D-backs recalled right-hander Silvino Bracho from Triple-A Reno.
