HOUSTON — Mike Vrabel's NFL playoff debut as a head coach will come against the team he helped win three Super Bowl titles as a player.

Don't expect the gruff second-year leader of the Tennessee Titans to reminisce about his time with the New England Patriots as next weekend's game approaches, though.

"I'm not emotional," Vrabel said. "I just know what's ahead and it's about being focused on the Patriots and how I get these guys prepared to go on the road. You're basically walking into the viper's den."

The Titans secured their playoff spot with Sunday's 35-14 victory over the Houston Texans, their NFC South rivals who had beaten them earlier this month in Nashville, secured the division title last weekend and had nothing to play for.

Derrick Henry rushed for a season-high 211 yards and three touchdowns for the Titans (9-7), who will now prepare for their intriguing first-round matchup at AFC East champion New England (12-4).

"I haven't had a paycheck with a Patriots logo on it since 2008," Vrabel said. "It's no different than coaching against them with the Texans or coaching against them last year. It's a huge challenge to go up there and try to win."

The Texans (10-6), who rested quarterback Deshaun Watson and other key players, were locked into the AFC's fourth seed when the Kansas City Chiefs earlier Sunday. Houston — which lost at home to the Titans for the first time since Jan. 1, 2012 — will host the Buffalo Bills (10-6) in the first round.

Ryan Tannehill threw for 198 yards and two touchdowns for Tennessee, and the offseason acquisition from the Miami Dolphins will make his playoff debut in his eighth NFL season. Titans rookie A.J. Brown had 124 receiving yards and a touchdown.

Watson was active on Sunday, but coach Bill O'Brien started AJ McCarron instead. Watson was listed as questionable with a back injury ahead of the game but said he was OK. Houston receiver DeAndre Hopkins was also active but did not play, and several starters, including receiver Kenny Stills, left tackle Laremy Tunsil and nose tackle D.J. Reader, were inactive.

"Once we were getting closer to the beginning of the game, it was pretty obvious that our seeding wasn't going to change," coach Bill O'Brien said. "So we decided to do those things in the best interest of the team."

McCarron threw for 225 yards with an interception and ran for a touchdown.

Tennessee was up by seven at halftime and extended the lead when Henry scored on a 3-yard run with 10:06 left in the third quarter. Henry returned after sitting out last week's home loss to the New Orleans Saints with a hamstring injury.

Houston then used almost nine minutes on a 16-play drive that ended with a 1-yard touchdown run by McCarron. He evaded the rush and dived into the end zone for the score that cut the lead to 21-14.

Tennessee made it 28-14 when Henry scored on a 1-yard run early in the fourth quarter. That touchdown was set up when Brown grabbed a nifty 47-yard reception between two defenders just before falling out of bounds.

The Titans padded the lead when Henry rumbled 53 yards for a touchdown with 2:54 left. He finished the season with a career-high 1,540 rushing yards, which leads the NFL, and 16 touchdown runs, which is tied with Green Bay's Aaron Jones for the league lead.

Henry became the third player in franchise history to run for 15 or more touchdowns in a season, joining Earl Campbell (19 in 1979 with the Houston Oilers) and LenDale White (15 in 2008).

"Coach gave us a great statistic before this game about how teams that won in the playoffs ran the ball effectively, and the teams that didn't, didn't win," Henry said.

The Texans scored a touchdown on their opening drive for the first time all season when Duke Johnson's 1-yard run provided the game's first points. The Titans answered on the next series as Tannehill threw a 51-yard touchdown pass to Brown.

Tennessee then went ahead when MyCole Pruitt capped a 16-play, 90-yard drive with a 1-yard touchdown catch in the second quarter.

Henry is the first Titan to lead the NFL in rushing since Chris Johnson had 2,006 yards in 2009. Henry, who won the Heisman Trophy in 2015 at Alabama, is the first Heisman winner to win the NFL's rushing title since Ricky Williams did it in 2002.

The Titans were aware Henry was inching closer to passing Cleveland's Nick Chubb for the title during the game, and Vrabel told him he was giving him two more carries to try to get it.

"And he ended up just needing the one," Vrabel said.

Added Henry: "When he said that, I knew I had to make something happen."

Now the Titans will try to make something happen at New England, which is trying to repeat as NFL champion and shares the record for most Super Bowl wins (six) with the Pittsburgh Steelers.

"We've got a bunch of fighters, a bunch of guys that believe in each other," Tannehill said. "Through the ups and the downs, we just kept trying to get better each and every week."
