The Houston Texans have interviewed Penn State's Bill O'Brien about their vacant head coaching job and there are more interviews still to be done next week, according to multiple media reports.

Houston team owner Bob McNair told the newspaper Saturday night: ``The process has been underway, and it continues. The process isn't over. We have other candidates to interview next week.''

The paper reports O'Brien met with McNair and general manager Rick Smith last week, and also has interviewed former Bears coach Lovie Smith and interim coach Wade Phillips.

ESPN is reporting, citing unidentified sources, that O'Brien is the ``overwhelming favorite'' to become the Texans' coach.

O'Brien is 15-9 at Penn State, guiding the Nittany Lions through two winning seasons despite severe NCAA sanctions.
