Mike Vrabel described the Tennessee Titans' offense as its own worst enemy after the top seed in the AFC slumped to a shocking loss to the lowly Houston Texans.

The Titans went into Sunday's encounter on a six-game winning streak, including victories over the Buffalo Bills, Kansas City Chiefs and Los Angeles Rams.

But that was remarkably ended by the Texans, who claimed only their second win of the season with a 22-13 triumph in sodden conditions.

Ryan Tannehill was intercepted four times, with a Titans attack missing Derrick Henry and Julio Jones scoring just 13 points against a Texans team that has given up the fourth-most (264) in the NFL.

The Titans also lost top receiver A.J. Brown to a chest injury, but neither Vrabel nor Tannehill made any excuses for a dismal offensive showing.

"I think we've seen Ryan perform at a high level," Vrabel said. "Offensive football at any level takes 11 guys.

"There was a lot of good football out there, unfortunately we turned the football over too many times. Our defense battled. Our offense was its own worst enemy."

Tannehill added: "We just kept shooting ourselves in the foot you know?

"Turnovers, turnover on downs, penalties. We shot ourselves in the foot all day. And we got to get better and it starts with me."

The Titans remain in top spot in the AFC with an 8-3 record, but could be unseated by the New England Patriots (7-4) should they lose in Foxborough in Week 12.
