National Football League (NFL)

Tennessee Titans

Following a string of COVID-19 infections among athletes of the Tennessee Titans, the team confirmed over the weekend that another staff member had tested positive of the novel coronavirus.

In response to the new confirmed case, the team said in a statement that the Titans' facility has been shut down. The team added that it is currently discussing with the league on how to move forward.

Four players have since tested negative of the virus and returned to the facility: Beau Brinkley (long snapper), Greg Mabin (defensive back), DaQuan Jones (defensive lineman), and Isaiah Wilson (offensive tackle).

Since Sept. 24, the Tennessee Titans have registered 24 confirmed COVID-19 cases, including 11 staff members.

New England Patriots

The plight of the New England Patriots was similar to the Titans as the weekend brought bad news. Defensive back Stephon Gilmore's COVID-19 test came out positive.

Gilmore was revealed to have had contact with Cam Newton (starting quarterback) before he tested positive Sunday. Newton, on the other hand, tested positive Wednesday.

There have been reports that the Gillette Stadium has been shut down due to the latest confirmed case within the Patriots. The new case has also forced the Patriots to move its game against the Denver Broncos to Sunday.

National Hockey League (NHL)

Edmonton Oilers

Early last week, the Edmonton Oilers revealed that team captain Connor McDavid has been infected with the novel coronavirus.

The team revealed that McDavid, the Oilers' star center, was experiencing mild symptoms and volunteered to self-quarantine in his home. McDavid's health will continue to be monitored as he isolates.

McDavid isn't the first NHL player to test positive of COVID-19 but he is the first known confirmed infection since the end of the postseason.

PGA Tour

In early September, PGA Tour Champions player Mark Calcavecchia tested positive for the novel coronavirus. He is 60 years old and at the time of his infection, he was scheduled to take part in a tournament in South Dakota.

Following his recovery, Calcavecchia referred to the recovery process as "miserable," adding that "every bone" in his body was in pain. "It's the worst I ever felt," the winner of the 1989 Open at Royal Troon, said.

Calcavecchia said it was a "minor miracle" that his wife, Brenda, and other people whom he had contact with before his positive came around did not get the virus.

Earlier this month, Calcavecchie returned to the golf field for the first time since he contracted COVID-19 and warned that the virus is "very real."

National Basketball League (NBA)

2020 was a huge year for the NBA, as it came with multiple downs with the shocking death of former Los Angeles Lakers star Kobe Bryant and his 13-year old daughter, Gianna, and the pandemic shutting down the season.

The season resumed later with a big announcement: staffers, players, and coaches will live in a bubble that was plastered-off to the rest of the world. The bubble meant players and everyone else who signed into the resumed season would be away from their families.

Doubters took to social media to question how the 2019-2020 NBA bubble would work and how huge of a let-down it would be for fans looking forward to the Finals.

The NBA management pushed through with the plan, implementing strict disinfection measures and monitoring of potential symptoms among everyone inside the bubble for three months.

On Sunday night, the Los Angeles Lakers took down the Miami Heat in an emotional 106-93 victory. Sunday's win was the Lakers' 17th championship title, and marked the end of a historical season that saw zero COVID-19 infections among bubble residents.
