Another positive test for the Tennessee Titans will keep the facility closed on Thursday and puts Sunday’s game against the Buffalo Bills in serious doubt.

The Titans learned of another positive COVID-19 result from Wednesday’s testing, ESPN reported, and an inconclusive test was confirmed as a positive as the coronavirus count for the franchise is at 23 (13 players, 10 team personnel) since Sept. 24.

Thursday afternoon, the Titans announced they put tight end MyCole Pruitt and practice squad defensive back Breon Borders on the reserve/COVID-19 list.

In three games (one start) on the season, Pruitt has three catches for 17 yards and a touchdown. Borders has played in 13 games over the past three seasons with Buffalo, Jacksonville and Washington, and has recorded seven tackles and a fumble recovery.

Off last week due to a postponement of the scheduled game against the Pittsburgh Steelers, the Titans have not been allowed in the team facility for more than a week.

Scheduled to return from their forced bye week to face Buffalo on Sunday, the Titans are likely looking at another week off, NFL Network reported on Thursday.

Complicating any scheduled adjustments being considered is that the Bills have a short week of prep ahead with a Thursday game next week.

The NFL is discussing possibly shifting the standard for playoff teams to include winning percentage as the primary factor to determine the expanded playoff field — over total wins — if teams wind up playing less than the scheduled 16-game regular season schedule, ESPN reported.
