Steve Clifford was diagnosed with dehydration and discharged from the hospital, reported Adrian Wojnarowski of ESPN.
Clifford was taken to the hospital during the Magic's 132-118 win over the Timberwolves.
Clifford "came down with an illness" in the third quarter.
"He just came over and said, 'You're going to have to take it,' and I didn't really know what it meant until I saw him walk off. It was kind of a shocker. But we're praying he's well," said assistant coach Tyrone Corbin, who replaced Clifford.
Clifford has been cleared to resume his coaching duties.
