Murphy said the pause would begin at 6 a.m. and go until Jan. 2. It covers all youth sports, but excludes college and professional athletics, Murphy added.
"We do not take this step lightly," said Murphy, a father of four. "As folks probably know I'm a huge sports fan and all of our kids play sports. I hope and intend to see the winter sports season in January."
The Democrat also said that the outdoor gathering limit would be reduced from 150 to 25 people beginning Dec. 7. The change won't affect outdoor dining, he said.
