Portland Timbers defender David Horst out six months after undergoing leg surgery

The Portland Timbers announced Monday that defender David Horst underwent successful surgery to repair a displaced tibial plateau fracture of his right leg and will be out an estimated six months.

The 27-year-old left Saturday's contest against Houston at JELD-WEN Field after rolling his ankle while awkwardly contesting a run into the area by Dynamo attacker Giles Barnes in the 15th minute. Horst crumpled to the turf, writhing in pain and had to be stretchered off the pitch. He was replaced by second-year center back Andrew Jean-Baptiste.

Horst only just returned to the lineup in 2013 for Portland March 30 against the Colorado Rapids after dealing with injury coming out of the preseason. 

At the moment, it appears Jean-Baptiste will be in line to take Horst's center back spot in the starting lineup — he has already made five appearances so far this season for Portland.
