MEXICO CITY—The United States men's soccer team escaped from snowy Denver with a crucial three points, but they did not arrive in Mexico City unscathed. Jermaine Jones, one of the most influential players on the team, suffered an ankle injury during the 1-0 victory over Costa Rica and will not be available for Tuesday's match (10:30 Eastern, ESPN).

You can see a photo of Jones' injury here. He is reportedly on his way back to Germany to have the ankle examined.

Jones, 31, is one of the most-capped U.S. players in recent years, making 28 appearances for the Yanks since his debut with the team in October 2010. In that time the Frankfurt, Germany, native has scored two goals and delivered five assists for the Americans.

More importantly, Jones is a rugged veteran who is impossible to intimidate. When things get chippy, there's a very good chance he is somehow involved. (In fact, Jones is often too nasty for his own good; he earned seven yellow cards for the U.S. national team in 2012—far more than any other player.) He would not have blinked an eye at the buzz swirling around Estadio Azteca on Tuesday; his self-confidence would have been very useful against El Tri's talented team.

Now that he's unavailable, Klinsmann may opt to start Maurice Edu in a holding midfield role—a position he is very accustomed to—against a team he helped defeat when the U.S. beat Mexico in Azteca last August. In that match, of course, Edu played central defense, and he may reprise that role. If that happens, Kyle Beckerman could start for Jones, but the Real Salt Lake captain may be a step too slow for Mexico's vaunted attack.
