FOXBOROUGH — In his first-ever playoff game, Dion Lewis accomplished something no player in the NFL had done before him. The Patriots running back became the first player to score a receiving touchdown, rushing touchdown, and kick return touchdown in a playoff game.

Sounds like a pretty good night, right?

“I feel like this is my worst game ever, actually,’’ Lewis said after the game.

Lewis’s trifecta — part of a 64-yard performance on 13 carries and two catches on seven targets — also included two fumbles, one of which the Texans recovered and turned into a second-quarter touchdown in just two plays. (Left guard Joe Thuney recovered the second.)

But it’s the mistakes, not the trips to the end zone, that stick with Lewis.

“Just putting my team in a bad position. I don’t think this is my best game,’’ Lewis said after the 34-16 victory. “I’m just disappointed I put my team in jeopardy so I’ve got a lot of work to do.’’

Lest it seem that Lewis is unduly harsh on himself, his tone was matter-of-fact, not self-mutilating. Lewis can’t be entirely disappointed in his performance, which accounted for 18 of the Patriots’ 34 points. He hadn’t scored a touchdown in the six games he played this season, but he had scored two by the end of the first quarter Saturday night.

He got the Patriots on the board early, catching a short pass from Tom Brady and running it into the end zone for a 13-yard score.

After the score, Lewis met fellow backs LeGarrette Blount, James White, and Brandon Bolden on the sideline and the group did a celebratory dance, locking arms in a huddle and bouncing side to side. After the game, however, he said he was just doing his job, which is when he gets one-on-one with a linebacker, as he did, he’s expected to beat the guy, after all.

“I’m supposed to,’’ Lewis said. “The coaches trust me to do that and my teammates trust me to do that so I feel like when I get those opportunities I have to win.’’

Lewis’s kick return touchdown came on the Patriots’ very next possession. After fielding Nick Novak’s punt at the 2-yard line, Lewis started to his left and then cut back to the right, leaving only Houston’s Brian Peters between him and the end zone.

“I knew that if I got past him I had a chance and only thing I was thinking about was don’t get caught,’’ Lewis said.

The 98-yard play was Lewis’s first kickoff return for a touchdown since high school and the Patriots’ first in a playoff game, but it still didn’t register much emotion from Lewis. He said he couldn’t remember the circumstances of his last return touchdown in high school (“I’m getting old!’’ he quipped). Lewis figured he’d take one to the house sooner or later.

“It was a great return, great execution, the guys made their blocks, all season, since I’ve been back there, we knew that we’d get one, we just haven’t had too many opportunities to take it out, deep kicks, so we knew there was going to be opportunity and I was able to hit it and guys did a great job for us,’’ Lewis said.

Finally, the rushing touchdown, which came in the fourth quarter on a 1-yard run against a Houston goal-line defense that had stuffed the Patriots on multiple occasions. Lewis sneaked through, completing his trifecta and giving his team a comfortable 16-point cushion.

Again, no big deal. After the game, Lewis was asked what he’d have thought if someone had told him he’d score all three ways in his first-ever playoff game.

“I can do that,’’ Lewis said.

Lewis is just as confident that he can fix his bout with fumbilitis.

“I know what I’ve got to do,’’ Lewis said. “I can’t tell you guys but I know what I have to do. It’s fixable, I know that, and I’m going to do whatever I can because if I don’t I ain’t going to play so I’ll get it fixed.’’

No one else was as troubled with Lewis’s performance as he was. Brady was free-flowing with the compliments.

“He made some big plays for us,’’ Brady said. “The kickoff return was incredible. The touchdown catch, he had a good touchdown run, so he did a great job.’’

Ditto Bill Belichick.

“He’s worked extremely hard,’’ the Patriots coach said. “He was working really hard last year at this time when the team was at the end of the season and in the playoffs last year. This year he has an opportunity to play. I’m happy for him. He’s worked hard. He earned it.’’

Praise him all he wants, Lewis is onto the AFC Championship game. It will be just his second career playoff game and, if the Patriots win it, all fumbles will be forgotten and Saturday will quietly go down as the night Dion Lewis made history, and didn’t really care.
