Miami Dolphins assistant head coach and quarterbacks coach Jim Caldwell is taking a leave of absence due to health issues..
"I will be stepping back due to some medical complications that require my full attention," Caldwell said in a statement Saturday. "I want to thank (owner) Stephen Ross, (general manager) Chris Grier, Coach (Brian) Flores and the rest of the organization for the support they have given me and my family."
Caldwell, 64, will serve as a consultant for the team during the 2019 season.
The former Colts and Lions head coach joined first-year head coach Flores' staff in February.
"Our focus is on Jim's health and supporting him in every way that we can," Flores said. "With his knowledge and experience, Jim has been an invaluable member to our coaching staff and will continue to serve as a sounding board for me throughout the season."
Caldwell had a 62-50 record as a head coach with Indianapolis (2009-11) and Detroit (2014-17). He took the Colts to the Super Bowl in his first season.
