Boston center Kendrick Perkins is confident he will play in Game Five on Sunday night as the Celtics look to secure the NBA Title, according to The Los Angeles Daily News.

Perkins sprained his shoulder in the third quarter of Game Four, and he reportedly favored the injury in practice on both Friday and Saturday.

"It's the Finals," said Perkins. "You've got to suck it up and go all out. I feel like I can go (tonight). The doctor feels the same way."

It is the same shoulder Perkins had surgery on two years ago.
