Miller's agent Joby Branion told the NFL Network television network Miller was resting at home and is "in good spirits." He added that Miller plans to speak publicly on Friday.
Miller is the second active NFL player known to have tested positive for the coronavirus.
On Wednesday, Los Angeles Rams center Brian Allen revealed that he is recovering from COVID-19 after also testing positive.
Allen said he has since gotten over his virus symptoms, one of which included losing his sense of taste. AFP PDSPDS
