Green Bay Packers All-Pro safety Xavier McKinney may not be back on the field until the team's game against the Detroit Lions in Week 1 of the regular season.

While the exact injury to McKinney wasn't disclosed, a low-level calf strain can take 2-3 weeks to heal. The Packers likely want McKinney, an All-Pro during his first season in Green Bay, to fully recover from a soft tissue injury before the start of the regular season.

Xavier McKinney addresses his training camp absence and shares a clear message about his Week 1 status with the Packers.
