Hall of Fame coach Don Shula was hospitalized for treatment of two medical conditions that apparently are not serious.
His wife, Mary Anne Shula, said Tuesday in a statement that the family anticipates a full recovery and return home.
"Coach Shula has been admitted to the hospital due to fluid retention and sleep apnea," she said. "The family is looking for a speedy recovery."
The 86-year-old Shula, the NFL career leader in victories, was inducted into the Pro Football Hall of Fame in 1997. He coached the Miami Dolphins for 26 years and won two Super Bowl championships. Miami's undefeated season in 1972 remains the NFL's only perfect season.
In February, Shula traveled to the Super Bowl to watch his son, Mike, who is the offensive coordinator for the Carolina Panthers.
