Jonathan Taylor is out this Sunday for the Indianapolis Colts, the former Wisconsin running back held back due to COVID-19 protocols.

The rookie running back does not have COVID-19 but his girlfriend contracted the virus while away on a trip. Taylor is in self-quarantine as a safety precaution.

The loss of Taylor, a second round pick of the Colts in April’s NFL Draft, is a big blow ahead of Sunday’s home game against the Tennessee Titans. Both teams are 7-3 and tied atop the AFC South.

Taylor has been solid his rookie season, with 518 rushing yards and four rushing touchdowns to go along with 227 receiving yards out of the backfield.

Twice an All-American at Wisconsin, Taylor holds the Big Ten’s record for most 220-yard rushing games. His final two years in Madison he won the Doak Walker Award as the nation’s top running back.

It is unclear if Taylor, because he personally has not contracted the coronavirus, will be available for the Colts next week when they play the Houston Texans.
