"I never had a serious injury where I had to get surgery," Carter said Wednesday in a conference call. "It was definitely different for me. I had to stay in a positive mind-set. My teammates, my roommates, and my coaches just helped me through the whole process. It's nice to be back with everybody."
He gave special credit to his roommates - tailback Bill Belton, wide receiver Allen Robinson, and cornerback/safety Adrian Amos.
"They helped by pushing me and letting me know it's not as bad as it seems," he said. "When it first happened, I couldn't really do anything with my right hand. They would sit around and talk to me when I was doing my rehab with the trainers. They were supportive through the whole thing."
With Carter good to go for the opening of preseason camp in August, Penn State's passing game will get a boost. The 6-foot-3, 247-pounder finished second on the Nittany Lions last season with 36 receptions and 453 yards gained.
Carter, who will be a redshirt sophomore, said his rehabilitation has gone well. Doctors initially told him he wouldn't be able to participate in any part of spring ball. But he is able to join his teammates running and pushing blocking sleds.
And he's catching passes again, too, having started that "a month or two ago."
"Of course, the doctor wanted me to relax and not catch passes," he said. "But I'm so used to catching passes. I would do it on my own. I can catch the ball with no pain. It was all about getting my feet back under me and being able to run routes."
Carter said the team's sense of togetherness has been strong. He said the matter of transfers - under NCAA sanctions, Penn State players may continue until early August to transfer to another school without having to sit out a year - is not a concern.
"That's not been an issue at all," Carter said. "After last year and that Wisconsin [win], we all bought into the system and liked where we're at. There's no reason to leave here. . . . Coach [Bill] O'Brien knows how to keep us here. We're definitely excited to be a part of this Penn State team. I don't foresee anybody leaving."
