EAST RUTHERFORD, N.J. — Boys just want to have fun.

Andrew Luck certainly didn’t have any when he sat out a Thanksgiving night loss with a concussion. He made up for it very nicely Monday night in a 41-10 romp past the inept New York Jets.

“To get back out there and do some decent things, that’s fun,” Luck said after throwing for four touchdowns, three to Dwayne Allen. “Sitting out is no fun.”

Not that Luck had to work very hard against the hosts, who were booed by a much-less-than-filled MetLife Stadium almost from the outset.

Luck missed last week’s loss to Pittsburgh, cleared the NFL’s concussion protocol on the weekend, and came back in style with a prime-time performance. He lifted Indianapolis (6-6) into a tie for the lead in the AFC South with Tennessee and Houston.

“The quarterback was outstanding,” coach Chuck Pagano said. “It’s always great to have your starting quarterback under center.”

Allen and T.Y. Hilton were his main targets as he went 22 of 28 for 278 yards, and they received little opposition from the Jets (3-9).

“It was a great night for everyone,” Allen said. “You hope that every night you go to play, it’s a night like that. It’s not realistic in the National Football League.”

This one couldn’t have come easier for Indianapolis. The Colts toyed with the lifeless Jets from the beginning, when New York’s Jeremy Ross got to only his 11-yard line with the opening kickoff return. A three-and-out gave Luck the ball, and seven plays later, he hit a wide-open Allen for a 7-0 edge.

Indy needed only four plays on its next series, with Allen even more open for a 21-yard reception to make it 14-0. At that juncture, the Colts had gained 120 yards, the Jets 6.

“I can’t put my finger on it, but it has made a big difference,” Luck said of getting out quickly. “To be up 7-0 (immediately) means a lot.”

Those yardage figures wound up 421 to 250. Indy scored its most points since Week 13 of 2014.
