JuJu Smith-Schuster enjoyed a breakout season last year and the expectations are even higher this year, especially with Martavius Bryant gone.

He isn't 100 percent yet due to a knee injury that no one will really elaborate on, but it's really frustrating Smith-Schuster, via Jeremy Fowler of ESPN.

“Just something that's been bothering me over time,” said Smith-Schuster of the injury. “Kind of just adds up and lets me know, ‘Yo, I need to get it checked out.' We got it checked out.”

“Once I'm able to run out there and put on the pads and be with my guys, it's like the whole game changes,” said Smith-Schuster, who finished the year with eight total touchdowns. “It's like I never left.”

Smith-Shuster finished with 917 yards receiving last year and was also a dynamic kick returner. Without being on the field during practice, it's valuable time that the young budding star is missing to get better.

With Martavius Bryant not in the mix this year, Smith-Shuster knows that he is going to have a bigger role this year and that he is also going to need to step up his game.

“I want it. I love it. This is why I'm here,” said Smith-Schuster of picking up the slack for Bryant, who was traded to the Oakland Raiders in April. “I love the game. Whatever they put on my shoulders, I'm going to carry it and do what I can do for this team.”

How long until Smith-Shuster is back on the field is still to be seen, but the sooner the better for all parties involved.
