Gomez day to day with neck strain after collision

MILWAUKEE -- Brewers center fielder Carlos Gomez was smiling but sore after straining his neck in an outfield collision with right fielder Ryan Braun on Saturday.

Gomez passed a concussion test after the Brewers' 7-4 win over the Rockies and was deemed day to day, though manager Ron Roenicke was not ready to say the Brewers dodged a bullet until after further tests Sunday morning.

"We'll see on that," Roenicke said. "I'm not sure. Tomorrow really is going to tell us a lot on where he is."

If the Brewers give Gomez a day off Sunday, he will actually get two days off because the team has an open date Monday before an Interleague series in Toronto. That helps. What hurts is that shortstop Jean Segura also made an early exit on Saturday with cramping in his left quadriceps, testing a bench that is only four players deep at the moment.

The Brewers' current backup at shortstop and center field is Elian Herrera. Because Herrera had replaced Segura in the sixth inning, Roenicke was forced to move Braun to center field after Gomez went down, with Mark Reynolds taking over in right. It was Braun's first professional appearance in center field -- including his years in the Minors.

The Brewers' Sunday series finale against the Rockies was scheduled for 1:10 p.m. CT. The team has two other outfielders on the 40-man roster: Logan Schafer and Caleb Gindl, each of whom has seen action in the Major Leagues this season. Schafer was absent from the Triple-A Nashville Sounds' starting lineup on Saturday for a game that began after Milwaukee's game ended.

At Miller Park, Braun and Gomez converged at full speed when the Rockies' Ryan Wheeler hit a soft double in the seventh inning, Gomez appearing to be caught on the right side by Braun's body as they passed. Gomez remained down on all fours after the play and was visited by head athletic trainer Dan Wright and Roenicke. After a few minutes, Gomez walked off the field.

"In the moment it was scary," Gomez said. "I felt tingly in my whole body. I was scared, so I [understand] when they make the decision to take me out of the game. It's really sore kind of in my ear from the impact, but nothing serious.

"I'll come tomorrow and see how I feel. If I feel fine, probably I play."

The moment was just as scary for Gomez's teammates.

"That one looked like it hurt a little bit, especially when 'Gomey' goes down," catcher Jonathan Lucroy said. "He usually doesn't go down for anything. It takes something pretty drastic happening for him to go down like that, so I knew he was hurt."

Gomez also took a blow to the head the night before, when he collided with Rockies second baseman Josh Rutledge's leg on a stolen-base attempt. Gomez remained in the game and said Saturday morning that he had a headache but did not undergo concussion tests.

"I'm really sore today from [Friday] night, and got hit again," Gomez said.

"Something really jarred him, so tomorrow they'll look at that again," Roenicke said.

Last year, Major League Baseball instituted a seven-day disabled list for concussions. It came from a recommendation of a committee formed to study the impact of concussions in baseball that included Brewers medical director Roger Caplinger.
