The past 48 hours have been a roller coaster of a ride for the Houston Texans. They went from a team on the verge of upgrading their secondary with one of the best defensive backs of the past decade in Earl Thomas, to conflicting reports to why the workout had stalled.

After hearing from head coach and general manager Bill O'Brien Wednesday morning via Zoom, here is a complete timeline of the events that took place between the Texans and their debacle with Thomas' workout, featuring the one and only — coronavirus.

A.J. Moore's injury opens the door for the Texans to sign Earl Thomas

When the Texans dropped their third consecutive game against the Pittsburgh Steelers, Houston also lost safety A.J. Moore in the process. The 24-year-old defensive back from Mississippi left Sunday's game with a severe hamstring injury and did not return. Monday morning, the Texans announced that Moore could miss up to three weeks.

With Moore placed on injured reserve, O'Brien and his staff felt it was time to search the free agency pool in hopes of finding a player who can help fill in the empty void at safety. Although several players on the market could have stepped in for the injured Moore (i.e. Eric Reid and HaHa Clinton Dix), the Texans arranged a workout for free-agent Earl Thomas set for Tuesday, September 29. Thomas — along with several other players — made their way to Houston late Monday afternoon for their respective workouts.

Thomas' fit with the Texans & "signing this week is more likely than not"

Virus outbreak alters Thomas' workout with the Texans

Early Tuesday morning, O'Brien and his staff received a call from the league office stating that eight members of the Tennessee Titans (now nine) tested positive for the Coronavirus. The NFL's first outbreak of COVID-19 led to several teams around the league to alter their plans for the week — including the Texans.

O'Brien said instead of having Thomas — along with several other players — held up in a hotel due to the uncertainty surrounding COVID; they felt it was in everyone's best interest to cancel all workouts scheduled for Tuesday. But instead of rescheduling, the Texans ceased Thomas' workout.

Speculations to why Houston canceled Thomas' workout altogether spread like wildfire. The most discussed reason, "the Texans decided Earl Thomas was not a good fit for their locker room." Both parties credited the latter. And late-Tuesday night, the outspoken future Hall-Of-Famer confirmed via Instagram that COVID was the reason behind his nixed workout with the Texans.

Ahead of practice Wednesday morning, O'Brien reaffirmed that Thomas' canceled workout was nothing more than concerns surrounding COVID. He has not ruled out the possibility of revisiting Thomas in the near future, so a potential signing could be put on hold for the time being.

"Earl Thomas is a hell of a player, he's had a great career," O'Brien said. "We had a bunch of guys in and we decided to cancel. We'll see how it goes moving forward. That's really what it was. It's not anything other than that. We've got a lot of respect for Earl."
