The Texans are currently in New Orleans for Saturday's preseason game against the Saints. After they return home, however, they could face a decision about next Thursday's preseason finale against the Dallas Cowboys.
Cowboys executive vice president Stephen Jones said there have been conversations about moving that game from Houston's NRG Stadium to AT&T Stadium in Arlington, if necessary.
"Let's see what happens," Texans coach Bill O'Brien told reporters Thursday about the Texans' plans to return home after Saturday's game. "Certainly if something does happen to that effect, we'll have to address it with our players. Family comes first. It's never football over family. It's football over a lot of things, but not family."
The Astros, who are on the road for a weekend series against the Los Angeles Angels, are scheduled to fly home Sunday night. They have an off day Monday before hosting the Texas Rangers for a three-game series and then the New York Mets for a three-game series beginning next Friday.
"Right now, we're in a holding pattern," Rangers traveling secretary Josh Shelton told the Fort Worth Star-Telegram of the team's plans to travel from Oakland to Houston on Sunday. "We'll know more once it makes landfall."
Harvey is expected to stall and let loose with lots of rain -- upward of 35 inches in some areas -- and then will likely go back into the Gulf of Mexico as a tropical storm, gain strength and hit Houston next week.
Hurricane Harvey has already forced the cancellation of some sporting events.
The Houston Dynamo called off Saturday's MLS game against Sporting Kansas City and rescheduled it for Oct. 11. Likewise, the National Women's Soccer League's Houston Dash will not play Sunday's game against the North Carolina Courage.
The Double-A Corpus Christi Hooks canceled both games of Friday's doubleheader against the Midland RockHounds.
Sam Houston State, which is scheduled to open its college football season against Richmond on Sunday, said in a statement Thursday that it is continuing to monitor developments before making a decision about the game.
"First and foremost, our thoughts and best wishes are with our neighbors in South Texas, and of course with our friends and family here in South Louisiana as Hurricane Harvey draws near," the university said in a statement. "We know all too well the challenges of facing a storm of this magnitude and stand ready to assist in any way we can."
In addition, the Houston Cougars have moved their football practices to Austin and will use the Texas Longhorns' indoor facility over the weekend. The Cougars are preparing to stay out of town until Tuesday, if necessary.
The Longhorns are entering their first season under Tom Herman, who coached the Cougars the previous two seasons.
