The Texans have lost their best players to injury throughout the season. Now they are losing their biggest offseason acquisition (by far) for a couple of weeks.

Mark Berman of FOX26 in Houston reports that defensive coordinator Wade Phillips will take a medical leave of absence for “a couple of weeks.”

It’s unclear what’s wrong with Phillips, but we wish him the best. Phillips has helped turn the 30th-ranked defense in the league into the top-ranked unit in yards allowed.

UPDATE 10:20 a.m ET: John McClain of the Houston Chronicle reports Phillips is undergoing a procedure. Linebackers coach Reggie Herring will call defenses until Phillips can return to the team.

UPDATE II 10:27 a.m. ET: The team confirmed the news. They say Phillips is expected to return later in the season. Phillips will address the media Wednesday.

UPDATE III 10:30 a.m. ET: Coach Gary Kubiak said on a conference call Wednesday that Phillips will miss two games.

“We’ve got to make sure Wade’s health comes first and get this taken care of so we can move forward,” Kubiak said via Joseph Person the Charlotte Observer.
