Jermaine Jones will be out 4-6 weeks after undergoing surgery to repair a sports hernia. Originally, Jones said he would be out "a couple weeks," but the New England Revolution said that the recovery time would be longer following Tuesday's operation.
With Jones set to miss at least a month, the Revs will not have him for the start of the MLS season. He will miss the season opener for sure, and it could end up being a three-match absence if he's out the full six weeks.
It is possible that Jones won't be available for the United States' friendlies against Denmark and Switzerland on March 25 and 31. He will only just be getting back from injury so even if he is back and playing, his fitness probably won't be great. Whether Jurgen Klinsmann wants to bring him in, especially for matches in Europe when he's in MLS, is unclear. But every match is key for Jones at this point, as he transitions to centerback and needs every rep with him still a midfielder for the Revs.
