Now 36, Hejduk joins the Galaxy after eight seasons with the Crew and an extensive career in Europe.
"[I'm] going back to my roots, where it all began," Hejduk told MLSSoccer.com. "What a great opportunity to get to play in front of my friends and family.
"Experience - you can't buy that, you can't teach that. It's something that's gained, so were going to bring that side to the team. The more experience a team can have, the better.
"With this team, especially, there is an incredible mix of not only incredible experience but a bunch of top-talent youth as well. It's going to mix really well."
