Rookie Channing Frye left the Knicks' 114-109 loss to the Toronto Raptors on Tuesday night with a sprained left knee ligament -- an injury caused when teammate Nate Robinson seemed to knock Andre Barrett into him, the Associated Press is reporting.

Barrett was racing upcourt with the ball with a little more than 9? minutes left when Robinson, chasing him from behind, appeared to try to swipe the ball away. Barrett lost his balance and fell into Frye's left leg.

"I apologized to him like 100 times already," Robinson said. "I definitely took full responsibility of what I did. Hopefully it's minor because I would hate for me to be the one to hurt his career or anything like that."

"It could have been a lot worse, but I'll be back," Frye said as he left Madison Square Garden on crutches.

"I kind of knew something happened, because I hit him hard," Barrett said. "And when I tripped I couldn't control myself and he's just standing there."

X-rays were negative, and Frye will remain in New York while his teammates head to Orlando to take on the Magic.
