INDEPENDENCE, Ohio -- Kay Felder (concussion) will miss the Cavs' season opener against the New York Knicks on Tuesday, coach Tyronn Lue said.

Felder, a rookie, was elbowed in the head at practice Friday by center Chris "Bird Man" Andersen and remains in the NBA's concussion protocol.

If you're trying to get a visual of what that may have looked like, Felder is 5-9 and Andersen is 6-10. The body-mass difference between the two is, well, sizable.

"(Felder) was working on some switching and trying to keep him out of the post so Bird was just trying to go and swim him out," coach Tyronn Lue said. "Kay is so little so when he did the swim he hit him with the elbow across his eye."

The Cavs will use combo guard Iman Shumpert as their second point guard, behind Kyrie Irving.

Lue also said DeAndre Liggins could potentially get a chance to back up Irving.

"Just have to see how Shump does," Lue said. "If he's comfortable with it and feels good when we're doing it then we will continue to roll with Shump."
