The Earthquakes signed veteran German right back Andreas Gorlitz as the club prepares for its MLS season opener March 15 against Real Salt Lake at Buck Shaw Stadium.
Per league and team policy, terms of the deal were not disclosed.
The Quakes will also host Mexico's FC Toluca on March 11 in the CONCACAF Champions League quarterfinals.
"Andreas is an excellent right back with a ton of experience," Quakes general manager John Doyle said in a club release. "He's great at getting forward, and we're excited to have him join the club."
After defender Steven Beitashour was traded to Vancouver on Jan. 27, Gorlitz, 32, and Brandon Barklage, a former New York Red Bulls regular, have been earmarked to fill the void at right back.
Gorlitz joins the Quakes after 12 years as a German professional. He began his career with TSV 1860 Munchen in 2001, and made 37 Bundesliga appearances over three seasons. The club transferred Gorlitz to Bayern Munich, where he started five games his first year, made two UEFA Champions League appearances and earned two national team caps. However, a torn anterior cruciate ligament suffered in a Champions League match against Juventus sidelined him until 2006.
Gorlitz returned to action with Bayern Munich II, making 21 appearances before returning to the first team in 2006-07. His was on loan with Karlsruher SC from 2007-09, before a brief return to Bayern Munich for the 2009-10 season. Gorlitz spent the next three seasons with FC Ingolstadt 04, making 63 appearances over two seasons making his way to the Earthquakes.
