Coach Sean McVay said Kupp doesn't have an ankle sprain but instead is dealing with pre-existing ankle soreness, Eric D. Williams of SI.com reports.
After Kupp left Saturday's practice with an injury, Ian Rapoport of NFL Network reported that the issue was a low-ankle sprain. Kupp underwent the requisite testing, including X-rays, and a sprain has been ruled out as the issue. While he may be held of practice in the short term, there doesn't seem to be much worry about his status for Week 1 versus the Cowboys.
