Kevon Looney left Game 5 of the NBA Finals after re-aggravating a chest injury that was originally supposed to keep him out for the remainder of the series. Had it not been for Andre Iguodala, it sounds like Looney would have kept on playing through it.

"Kevon couldn't play tonight," Iguodala told reporters after the game. "I had to tell him, 'Don't play anymore.'"

Iguodala also spoke on the "brotherhood" among the Warriors and what it means to play through pain.

"We always talk about how this team is with one another, but people still don't really grasp what we're talking about," Iguodala said. "When we say this is a real brotherhood with this team, people have no clue what goes into that."

Looney has been playing through a 1st costal cartilage non-displaced fracture, and left the game in the third quarter after fighting for a rebound with Raptors point guard Kyle Lowry.

He said after the game he hopes to play in Game 6, if the Warriors let him. He was told he wouldn't make the injury worse by playing, but might feel added pain or discomfort.

"They're comfortable with me going out there as long as I can tolerate the pain," he said. "I feel like I should be able to play in Game 6."

Looney first suffered the injury in Game 2 and was originally expected to miss the remainder of the series before surprisingly returning for Game 4 last week.
