The Tennessee Titans had no new positive tests for the novel coronavirus in results returned Monday morning, keeping their rescheduled game Tuesday night against the Buffalo Bills in Nashville on course to be played.

The results were confirmed by a person familiar with the situation. The Titans have had the NFL’s first widespread outbreak, with 24 positives since Sept. 24, including 13 players and 11 staff members. Their facility was temporarily closed Sunday morning after a positive test result for a staffer. It had just reopened Saturday following an 11-day shutdown.

But the Titans held an outdoor practice for 1 hour 45 minutes later Sunday, with limited staff on hand, after being given permission to do so by the NFL, the team announced.

The New England Patriots likewise had no new positive tests in Monday morning’s results, according to two people with knowledge of the results. The Patriots also closed their facility Sunday morning after it had reopened Saturday.

The Patriots are scheduled to play Sunday against the Denver Broncos in Foxborough, Mass. That game first had been postponed to Monday night, then was pushed back further after the Patriots had a positive test result Sunday morning. The further postponement of the Patriots-Broncos game was among eight changes announced Sunday by the league; a series of schedule maneuvers was required to accommodate the playing of the Patriots-Broncos game on Sunday since the Broncos previously had been scheduled to face the Miami Dolphins that day.

The NFL has been contemplating adding an 18th week to the regular season schedule to accommodate rescheduled games but apparently would like to wait until that is necessitated by the postponement of any games that cannot be rescheduled otherwise.

Meanwhile, the NFL and the NFL Players Association have added game-day coronavirus testing of players, coaches and selected team staff members to their testing protocol. The league informed teams of the change in a memo Monday. Testing previously had been conducted six days per week, with the possibility of point-of-care tests on game days under certain circumstances. Game-day testing also had applied to teams suffering an outbreak or exposed to one, under enhanced protocols. Now it will take place for all teams.

The regular testing on game days will not determine the eligibility of players and coaches for that day’s game; the results of the standard tests aren’t returned that quickly. Instead, this update to the protocols closes the gap that had existed in testing.

NFL owners are scheduled to meet remotely Tuesday and Wednesday. It is their regularly scheduled October meeting, but Tuesday’s discussions are expected to cover the sport’s recent coronavirus-related issues.
