The last time Luke Kuechy missed a football practice, he was living with his parents. He was a freshman at St. Xavier High School in Cincinnati, still seven years away from becoming the Carolina Panthers' first-round pick in the 2012 draft.
So while his teammates practiced nine times and played three games without him the past month, the Pro Bowl linebacker couldn't help but feel left out.
"You’re sitting in here and all the guys come in, they’re all sweaty, they had a good practice, they’re all joking around about what happened at practice," Kuechly said Tuesday after returning to practice. "It’s like you’re in time out and you can’t go out and play with your friends. It’s like detention and they’re at recess and you can’t hang out with them."
Kuechly, who had been in the NFL's concussion protocol since Week 1, was cleared after meeting an independent neurologist on Monday.
"It's like he picked up right where he left off, communicating, running around all over the place, doing things that are typical of Luke," coach Ron Rivera said. "It was a long process, but the process was what it needed to be."
If that process seemed longer than usual, it's because Kuechly's situation proved how the NFL has changed. Or at least, is changing.
It's easy to be cynical about a league that took so long just to acknowledge players' brains may be at risk in a sport that requires the head to take and give hits at high velocity. But over the past few weeks, Rivera admitted he would have likely played Kuechly in the 'old days,' and there's no question players need to be protected from themselves.
"I would have played as much as I could," Kuechly said. "But it's one of those things, what's the smart thing to do, what's the right thing to do, versus what you want to do. Obviously I want to play every game, but you understand that stuff has to be taken care of or else you may get another one.
"It’s weird, you can’t tape it up, you can’t suck it up. It’s one of those things that you’ve just got to wait for it to go away. That was probably the most difficult part, knowing that you can’t really tough it out."
Kuechly said this was his first career concussion, despite playing a position that is one of the most susceptible in football.
"Sometimes when you’ve been playing, sometimes you wonder do I know I have one. And I knew I had one," Kuechly said. "It’s hard to explain. You have headaches, stuff’s just quite not right. And that’s the best way to describe it.
“Now everything is back to full speed and good to go.’’
But how good to go will he be immediately? After missing an entire month, Kuechly may sit out a handful of snaps in Seattle.
"I can see us doing certain things in terms of pitch counts, just keeping an eye on how many snaps he's getting," Rivera said. "We feel very comfortable with A.J. [Klein]. He's proven he can play the middle for us as well, not just as an outside backer, but he can play the middle for us."
Kuechly's conditioning may be a concern for coaches, but he's confident he'll be back in football shape soon. Besides, at least one teammate believes Kuechly is almost superhuman.
"He's one guy I know that he never show up fatigued, so I never notice he get tired," defensive end Mario Addison said. "I don't think he gets tired; he's like Superman. Luke is like Superman."
Football, of course, isn't a comic book. We know the characters we watch on the field are tough, but they often see themselves as invincible. Yet while many wondered why it took so long for Kuechly to return, it's because he's not superhuman. There may not have been visible signs of an injury, but Kuechly's "detention" was the best thing for him.
"I was told as long as you give it time and let it heal you’re not going to be any more susceptible to one in the future," Kuechly said.
"We know a lot more about it now. What we set up here and what the NFL has set up is very beneficial."
