Warriors forward David Lee injured his right middle finger at Team USA training camp Tuesday.
Lee, acquired from the New York Knicks earlier this month, was expected to fly back to the Bay Area on Tuesday night. He has a visit scheduled with San Francisco hand specialist Dr. William Green, who last week performed the surgery to repair torn ligaments in the left wrist of Warriors rookie Ekpe Udoh.
Lee told ESPN.com that the injury occurred when he went up to block a shot and jammed the middle finger of his shooting hand against the bottom of the backboard.
"I looked down and my finger was completely turned to the side," Lee said. "It's possibly a tendon or a dislocation of some sort. It's something I've got to go have looked at either way. Hopefully it's something I can splint up and play with. That's up to the doctors to decide."
Team USA opened practice Tuesday at UNLV's Cox Pavilion in preparation for next month's World Championships in Turkey.
Lee signed a six-year, $80 million contract with the Knicks just before being traded to the Warriors in exchange for Anthony Randolph, Ronny Turiaf and Kelenna Azubuike. He and Warriors point guard Stephen Curry are among some 20 players who are vying to make Team USA's roster for the World Championships.
Lin played for the Dallas Mavericks' summer league squad in Las Vegas and piqued the interest of several teams with his performance. But the former Palo Alto High star is signing with the Warriors, his favorite team growing up.
Lin could become the first American-born Asian to play in the NBA since current USF coach Rex Walters, whose last year in the league was in 2000. The first was Walt Misaka, who played three games for the New York Knicks in the 1947-48 season, back when the league was called the Basketball Association of America.
The Warriors need a point guard after trading C.J. Watson to the Chicago Bulls, a deal that has yet to be finalized. Lin is going to get his chance to fill that void, but he has some developing to do.
Lin has the game of a shooting guard with some point guard skills. But he'll need to make the transition to a full-time point guard in the NBA, which makes him more of a project behind starting point guard Stephen Curry.
So the Warriors — who have three open spots after Lin signs — still could go get a proven veteran as the backup point guard. That would allow Lin to develop without pressure.
Even if they don't add another point guard, Golden State still have combo guards Monta Ellis and Charlie Bell as options behind Curry.
