San Diego ? Reigning NFL MVP LaDainian Tomlinson was one of 40 members of the San Diego Chargers’ organization who were forced to evacuate their homes as wildfires burned in San Diego County, and the team will spend the rest of the week practicing in Arizona.

The Chargers, who had just returned from their bye weekend, canceled practice Monday due to poor air quality and so the players could take care of their families, spokesman Bill Johnston said.

The Chargers, scheduled to play host to Houston on Sunday, announced they will fly to Phoenix today to practice at the Arizona Cardinals’ headquarters on Wednesday, Thursday and Friday.

The Cardinals have a bye this weekend.

“Our team is more than willing to accommodate them,” Cardinals spokesman Mark Dalton said.

“Our overwhelming priority now is the safety of our players and staff and their families,” the Chargers said in a statement. “Our prayers are with everyone who is impacted by this tragedy.”

Four years to the week after moving a Monday night game to Tempe on short notice because of deadly wildfires, the Chargers and the NFL said it was too early to know if the fires will affect Sunday’s game.

“We are monitoring,” NFL spokesman Greg Aiello said in an e-mail.

Wildfires fanned by fierce desert winds forced the evacuations of nearly 250,000 people in the county.

There was no immediate word if any Chargers employees had lost their homes. Many Chargers players, as well as other current and former pro athletes, live in Poway and other suburbs in northern San Diego County.

If the Texans-Chargers game is moved to Arizona, Houston coach Gary Kubiak said he heard it could be played Sunday night or Monday night.

Trevor Hoffman, baseball’s career saves leader, was among a handful of Padres personnel who had to evacuate. Also leaving their homes were manager Bud Black and CEO Sandy Alderson.

Hoffman said he left his home in Rancho Santa Fe about 6:30 a.m. and was heading north with his family.

“I’m just thinking about San Diego as a whole right now, being under siege by all these fires,” Hoffman said by cell phone.

Baseball Hall of Famer and current San Diego State coach Tony Gwynn and his wife left their Poway home at 6 a.m. and were waiting out the fire at their daughter’s house in Mission Valley.
