Notre Dame tight end Kyle Rudolph had a quiet game against Stanford last weekend.
Rudolph, who entered the game leading all tight ends with 21 catches for 287 yards, had one catch for one yard against the Cardinal.
Part of the lower production was Stanford's defense using eight defenders to cover against the pass, and another part was Rudolph's physical well-being.
"I wasn't myself, I'll tell you that," Rudolph said Wednesday.
The 6-foot-6, 265-pounder said he tweaked his hamstring trying to break a tackle after his catch Saturday.
The cool temperatures also didn't help Rudolph, who was slowed during fall camp by the injured hamstring.
"It was just something I couldn't get going," Rudolph said. "Whether it was re-aggravating it, the weather, we did everything we could from a medicine standpoint with the trainers to get it warmed up and get it loosened up. And it was something that just nagged for the whole day."
Rudolph wouldn't put a percentage on how he felt against Stanford, but he did say he feels he will be at full strength when the Irish play Boston College this weekend.
"I feel very comfortable with the things we've done, leading up 'til now," Rudolph said. "I feel like I'll be 100 percent on Saturday."
