The New England Revolution's Matt Turner will likely be sidelined for a couple more weeks by an ankle injury, raising the possibility the United States will be without its top two goalkeepers when World Cup qualifying resumes on March 24 at Mexico.
Revolution coach Bruce Arena said during a news conference on Tuesday that Turner was injured during a practice game at LAFC. New England said it was during a closed-door scrimmage that took place Feb. 9.

"A foot, ankle injury," Arena said. "Timeframe, probably a couple of weeks from now he'll be available."
The 27-year-old Turner, who has agreed to a summer transfer to Arsenal, has not played a competitive match since Feb. 2, when the United States beat Honduras 3-0 in St. Paul, Minnesota.
Turner missed New England's Feb. 26 opener away to the Portland Timbers and Saturday's match against FC Dallas, and he will not be available for Wednesday's CONCACAF Champions League quarterfinal first leg against Liga MX side Pumas.
He has supplanted Manchester City's Zack Steffen as the top U.S. goalkeeper in World Cup qualifying, starting eight of 11 matches.
Steffen has not played for Manchester City since Feb. 5 and has not dressed since Feb. 9 due to back and shoulder injuries.
New York City FC's Sean Johnson and the Chicago Fire's Gabriel Slonina were the other goalkeepers on the roster for January World Cup qualifiers.
Ethan Horvath, who was on the September roster, had not played for Nottingham Forest since Sept. 15. He then started three straight league matches due to Brice Samba's red card against Stoke, which carried a three-game suspension, and also started an FA Cup match.
