The United States released its preliminary roster for basketball at this summer’s Olympics back in mid-March, but since then, a flurry have injuries have becursed Team USA and put the program in a tricky position with London on the horizon. Now, according to USA Basketball director Jerry Colangelo, some additions may have to be made.

From the AP’s Brian Mahoney:

US can't field allowable roster of 12 + 6alternates, so Colangelo on adding guys: "Probably when all's said and done, the answer's yes."

Of the original 20 players on Team USA’s list, five (LaMarcus Aldridge, Chauncey Billups, Dwight Howard, Kevin Love and now Kevin Love) have become serious injury concerns, and a sixth (Lamar Odom) has deteriorated for other, off-court reasons. The Americans are running desperately low on bodies for this summer’s Games.

If Colangelo does decide to add more talent, there’s no shortage of available guys to choose from. Among the star American players omitted from the original list are Andrew Bynum, Josh Smith, James Harden and Rajon Rondo. Presumptive No. 1 draft pick Anthony Davis could also make for a wild-card selection.

The preliminary basketball rounds at this summer’s Games begin on July 29 at London’s Olympic Park.

New York Knicks point guard Jeremy Lin could be invited to train with the U.S. Olympic team, according to a tweet from ESPN’s SportsCenter account.

Longtime sports executive and director of USA Basketball Jerry Colangelo told the New York Times he cannot recall anything similar to the way Lin came out of nowhere, reinvigorating a struggling Knicks team and becoming an international hero.  Although he gave the point guard such high praise for his accomplishments, Colangelo  also noted that Lin will not be placed on the USA Basketball team roster telling the New York Times, “the players who already have time invested in the system have equity built up.”

That, however, does not mean he will not be invited to train with the team.

When discussing the possibilities of which players have the best chance at filling the team’s point guard spot, Colangelo and Team USA coach Mike Krzyzewski noted it would be quite difficult for Lin to beat out the current top point guards in the league.  Despite Lin’s outstanding play thus far, he would have to outplay Chicago Bulls’ Derrick Rose, Oklahoma City Thunder’s Russell Westbrook, Los Angeles Clippers’ Chris Paul, and New Jersey Nets’ Deron Williams.
