Fabian Johnson and Darlington Nagbe limited in Monday training

One of the biggest questions surrounding the United States prior to Jurgen Klinsmann's roster selections was the sudden rash of injuries that cropped up. First it was Fabian Johnson on Friday picking up a thigh strain in a match with Borussia Monchengladbach. Then it was Darlington Nagbe suffering a vicious tackle in the dying moments of the Portland Timbers 2-2 draw with Real Salt Lake.

It was feared that both would be in danger of missing these two important qualifiers against Guatemala with the injuries occurring so close to the roster announcement. Those concerns were alleviated when Klinsmann's 26-man list finally came out and both player's names appeared.

However, the risk of either missing some kind of action hasn't completely subsided. Even though both are on the roster, the pair were limited to gym work on Monday according to ESPNFC and are day-to-day in their recovery status.

Johnson is obviously a huge key to this USMNT side. Getting him fully fit and ready for Friday night is probably at the forefront of Klinsmann's concerns at this point. He's in arguably the best form of his life this season in the Bundesliga. If he's able to replicate that with the national team, he could be the difference maker the team has been looking for since Landon Donovan departed the team.

Having a quality player like Nagbe in the fold is always helpful. His availability isn't as paramount as Johnson's, but having him available for selection is always a benefit to any team he plays on due to his technique as a player and his versatility.
