When Clemson begins classes on Wednesday, Dabo Swinney is hopeful his freshman wide receiver Deon Cain will be in class, but he will not be with the football team.

Cain has been suspended from the National Championship Game after failing a drug test prior to last week’s Orange Bowl win over Oklahoma. He, along with former kicker Ammon Lakip and former tight end Jay Jay McCullough, were sent home prior to the game after Clemson learned of the results.

All three were suspended for the remainder of the post season, ending Lakip’s career. McCullough, who will graduate in May, will not return to the team, but Swinney said he can transfer to another school to finish out his final season.

As for Cain, Swinney hopes he has learned his lesson. This is the second time he has been suspended from a game for disciplinary reasons this season. He was forced to sit out the Miami game earlier this year for a violation of team rules.

“As I said (in Miami), he has to grow up. He has to make a decision if he wants to be a great player at Clemson,” Swinney said. “But if you want to be a great player at Clemson then you have to follow the rules. It is just that simple or otherwise you have to go somewhere else.”

Before the suspension from the Orange Bowl, Cain had emerged as Deshaun Watson best deep threat. In the six games leading up to the Capital One Orange Bowl, Cain was targeted 26 times, and 21 of those went for completions. Five of them went for touchdowns.

Cain’s 319 yards on 21 receptions both ranked third on the team during that stretch, while the five scores led the team. Clemson, who will face No. 2 Alabama in the National Championship Game next Monday, will no doubt miss a guy who has caught touchdown passes of 55, 40, 40 and 38 yards in the last six games.

“I hope he’ll figure that out. I hope that he will be back tomorrow and he will make a decision that this thing is not about him. It really is not,” Swinney said.

Cain played in 12 games this year and is fourth on the team in catches with 34 for 582 yards and five touchdowns.

With Cain out, Clemson turned to former walk-on wide receiver Hunter Renfrow. The redshirt freshman responded with four catches for 59 yards, including a 35-yard touchdown.

“I don’t mean this in a negative way, but our walk-ons scored more points than Oklahoma’s team in the ball game,” Swinney said. “I think that is a great message to a guy like Deon Cain. Greg Huegel and (Hunter) Renfrow scored more points … 19 points, more than the whole team of Oklahoma. I think that sends a message – we can win without you.

“Hopefully, he is going to do what he needs to do because at some point you have to grow up. If he does not want to grow up then he will not have an opportunity to be on this team again. But if he does the things he needs to then he’ll have a chance to come back. But that is all on him. I can’t do that for him. I can’t do it for him. I can’t do it. My job is to help him grow into a great person and a great man. That’s what I’m trying to do. That’s my number one job, to develop these guys into men. It does not matter to me what type of talent they have. I’m here to serve their heart, not their talent and that is what I’m trying to do with Deon.”
