Ex-Lions WR Calvin Johnson attends Dolphins practice

Allen Park — With an open invitation to attend a Detroit Lions’ training camp practice, former wide receiver Calvin Johnson made an appearance Monday at Miami Dolphins practice.

Johnson was invited to Miami’s practice by receivers coach Shawn Jefferson, who coached with the Lions from 2006-12. Johnson offered tips and advice to the Dolphins’ receivers and is reportedly expected to be sticking around the team’s facility the next few days.

Earlier this offseason, Johnson attended an Oakland Raiders practice in a similar capacity. Todd Downing, the team’s new offensive coordinator, worked as a quality control coach and quarterbacks coach for the Lions from 2009-13.

Johnson, who retired after the 2015 season, has been publicly critical of the Lions in recent months, taking umbrage with the way the organization treated him on his way out, and admitting part of the reason he called it a career is because he didn’t see any way the team could compete for a Super Bowl.

The Lions’ brass has expressed disappointment with the strained relationship and president Rod Wood announced during a radio interview that he had invited Johnson to training camp.
