Eric Thames replaced Wells in right field.
"He took a swing in the batting cage and his neck locked up," manager Eric Wedge said. "It locked up pretty good on him, so we've got Thames in there."
Wedge wasn't happy with his team's defense late in Friday's 9-3 loss to the Rangers and was looking for Wells to bolster that situation. The 25-year-old has played excellent defense in his opportunities this year while hitting .222 in 239 at-bats in 80 games.
Wells is 1-for-9 since being recalled from Triple-A Tacoma earlier this month. He played in six of the first nine games since being brought back, but the last three were all as a late-inning defensive replacement.
