FILE - In this April 20, 2013, file photo, Penn State coach Bill O'Brien answers questions during a news conference in State College, Pa. Two people familiar with the negotiations said Tuesday night, Dec. 31, 2013, that O'Brien has reached an agreement to coach the Houston Texans. The people spoke to The Associated Press on the condition of anonymity because an official announcement hasn't been made.

After guiding Penn State to two winning seasons despite crippling NCAA sanctions, coach Bill O’Brien has reached an agreement to become head coach of the NFL’s Houston Texans, according to several news outlets.

The news was first reported late Tuesday night by ESPN, which quoted league sources. The Houston Chronicle said the agreement would be announced formally on Thursday and that O’Brien would be in attendance.

There was no word on the length of the contract nor how much it will pay O’Brien, 44. The coach is on the hook for a buyout of close to $6.7 million, presumably to be taken care of by Houston, to get out of his Penn State contract, which still had 31/2 years left to run.

The NFL Network quoted sources as saying that O’Brien agreed to the deal right at the deadline the Texans had set.

O’Brien led Penn State to a 15-9 record in his two seasons, with his final game an upset victory at Wisconsin. More important, he stabilized a program that could have fallen apart after NCAA sanctions were imposed in response to the Jerry Sandusky child sexual abuse scandal.

But O’Brien, a former New England assistant who flirted with the Eagles and Cleveland a year ago before returning to Penn State, wanted to become an NFL head coach, and said his first responsibility was to his family to check out any opportunities.

The Texans, who fired Gary Kubiak as coach on Dec. 6, met with O’Brien on Thursday at O’Brien’s home on Cape Cod and reports surfaced that they would try to get a deal done as soon as possible. Team chairman Bob McNair also interviewed former Chicago Bears coach Lovie Smith and interim Houston head coach Wade Phillips, but O’Brien was his man all along.

The decision was believed to be a difficult one for O’Brien. His first recruit, quarterback Christian Hackenberg, stayed with his pledge even after the NCAA sanctions came out and had one of the finest seasons of any freshman in the country in 2013. Hackenberg’s father told the Harrisburg Patriot-News over the weekend that he was “comfortable” with what O’Brien told his son but did not disclose what that was.

In addition, the Nittany Lions have a recruiting class for 2014 that ranks in the top 20 by most recruiting websites. One recruit, four-star defensive tackle Thomas Holley, said O’Brien told him on Saturday that he was staying at Penn State.

Led by athletic director Dave Joyner, the university will need to act quickly to hire a new coach, keep the current staff intact, and hold on to the recruits.

Among the candidates mentioned are head coaches Mike Munchak of the Tennessee Titans, Al Golden of the University of Miami and James Franklin of Vanderbilt, as well as fired Tampa Bay head coach Greg Schiano and former Indianapolis Colts head man Jim Caldwell.

Munchak, a former Penn State star, is expected to learn his situation as a meeting with team officials later this week. Golden also played at Penn State, and Schiano and Caldwell are former assistants.

Among the Twitter postings of players after the O’Brien news was made public came one from defensive end Deion Barnes, the former Northeast High star.

“It’s crazy that I’ve been with PSU for 3 years now and I’m going to have 3 different coaches,” Barnes said. “We’ve been through it all and we gonna keep it up.”

O’Brien, who was offensive coordinator for the last of his five years with the Patriots, accepted the Penn State job on Jan. 6, 2012, two months after Sandusky was indicted.
