FOXBORO -- Rob Gronkowski told reporters on Monday that the groin injury he suffered in New Orleans the day before isn't serious.

"The reports say out there it was my groin, and yes it is my groin," Gronkowski said. "It's nothing serious, and I'm just day-to-day."

Gronkowski added he has no concerns about his back, which needed season-ending surgery last fall.

"No," he said. "Not at all."

Gronkowski opted not to speak with reporters following Sunday's win over the Saints, 36-20, but he did flash them a smile in the visitor's locker room and tell them, "I'm good."

The 6-foot-6 tight end left the game in the second half after making his sixth catch of the day, which gave him 116 yards and a touchdown. He was slow to get up, and when he did, he immediately gestured toward the Patriots sidelines. 

After speaking to trainer Jim Whalen and team physician Dr. Mark Price, Gronkowski underwent further evaluation in the Patriots medical tent on the sidelines. When he emerged, he remained on the Patriots sideline, pedaling a stationary bike briefly. 

The injury was later announced as a groin issue and he did not return.

"Super relieved," Gronkowski said Monday. "I knew there was nothing really wrong from the beginning. I'm good."

Will he be able to play on Sunday at Gillette Stadium against the Texans? To be determined.

"I feel good," he said with a smile. "Nothing serious."
