No sooner had RSL learned that starting defender Nat Borchers did not break any bones when he injured his right foot against the Los Angeles Galaxy than it received bad news on another front.

Turns out, back-up David Horst tore the meniscus in his right knee, during his 21 minutes in relief of Borchers. Horst played well and finished out the game, but according to a team spokesman, arrived at practice today complaining about pain in his knee. An MRI exam confirmed the tear, and Horst will have surgery on Friday to repair it — meaning he will be out four to six weeks.

That leaves RSL pretty thin in central defense, particularly if Borchers is out for a prolonged period.

Presumably, that would leave Jamison Olave and Robbie Russell to start in the middle, with probably left back Chris Wingert — who played centrally in college and early in his pro career — and perhaps rookie Jean Alexandre as potential substitutes.
