Real Salt Lake center back David Horst has joined the club’s list of the injured, with the player announcing on Instagram that he underwent a successful surgery to repair a torn right achilles tendon.

Horst, 32, played five matches for RSL in 2018. It’s difficult to know now whether Horst will play again for the club this year.

Horst joins Tony Beltran, Jordan Allen, Alex Horwath, Shawn Barry, Luke Mulholland and Demar Phillips as players with extended injury-enforced absences in 2018.

Having rejoined RSL in 2017 after extended runs with Portland Timbers and Houston Dynamo, Horst has served largely in a backup role, serving spot duty when other center backs have been out of contention.

With Justen Glad having suffered what seemed to be a concussion last week, RSL’s center back depth is now paper thin, with Marcelo Silva and Nick Besler ostensibly the only two fit center backs available.
