"It felt a little bit bad even before the game, but I really didn't think it was too much," Altuve said. "Just hit a fly ball and [the pain] got me pretty good when I turned."
The All-Star went hitless, going 0-for-3. However, he did drill a ball to deep center field that was caught at the warning track with two outs and the bases loaded in the second inning.
Manager Bo Porter said his second baseman is day to day.
"Just neck discomfort and more a spasm than anything," Porter said. "… We'll see how he feels when he comes in tomorrow. He made a quick move and you have discomfort. He couldn't really turn his head, so at that point, we got him out of the game."
Altuve's average dropped to .333 -- he was tied for the the American League lead in batting with Seattle's Robinson Cano at .335 entering Friday night. Altuve's average is 14 points off his season high of .347 from back in July.
Altuve has been by far the most durable Astro this season, playing in 113 of the team's 116 games, including Friday night's contest. Part of that can be attributed to Altuve's disdain for missing a game, especially with injuries that aren't bad enough to send him to the 15-day DL.
True to form, he doesn't believe this neck issue will cause him to miss subsequent time.
"No, it shouldn't [be serious]," Altuve said. "I should be ready [Saturday]."
Reserve Gregorio Petit replaced Altuve at second base and plated an important insurance run with an eighth-inning RBI double for a 4-2 lead.
