Their quarterbacks coach worked Mettenberger out a week ago, and coach Ken Whisenhunt said they considered selecting the quarterback sooner in the draft.
The 6-foot-5, 252-pound Mettenberger threw for 3,082 yards and 22 touchdowns last season. He tore his left ACL in the regular season finale in November and had surgery in January. Mettenberger said he was ecstatic for the opportunity and asked about not being drafted until the sixth round, he called this a great opportunity.
"I'll make the most of it, and I'm ready to get up there and get working," said Mettenberger, the 10th quarterback taken in the draft.
Mettenberger started his college career at Georgia where he redshirted as a freshman and was competing with Aaron Murray for the starting quarterback job. He went to junior college before landing at LSU where he worked last season with former NFL coach Cam Cameron as his offensive coordinator.
The Titans sent their seventh-round draft pick to Washington to move up in the sixth round. That left them with six selections in this draft, their fewest since 2003.
