Nicolas Lodeiro is recovering right knee surgery -- again.
The Seattle Sounders midfielder had an arthroscopic procedure Monday in Chicago and is sidelined indefinitely, the club announced.
Lodeiro had a similar procedure on the same knee in May, keeping him out for three months.
He returned to action last month and gradually worked his way into the team's plans, making four substitute appearances before starting three games. Lodeiro didn't play Saturday in the Sounders' 1-0 loss to Real Salt Lake in Sandy, Utah.
The 32-year-old Uruguayan has appeared in just seven of the Sounders' 24 league games this season, logging no goals and one assist.
Lodeiro, who joined the Sounders midway through the 2016 season, has averaged 7.3 goals and 12.5 assists in his four full seasons with the club.
The Sounders did announce a positive injury update Monday, as coach Brian Schmetzer said forward Jordan Morris was progressing nicely in his recovery from a torn anterior cruciate ligament. Morris sustained the injury in February while playing for on loan for Welsh team Swansea City.
"Once he gets a few more training sessions in, we'll open him up to full training, but he's getting closer," Schmetzer said. "He looks good to me. I'd put him into full training, but I'm not a doctor.
"He looks like he's ready, he's a competitive kid, he's itching to play. ... As soon as he's in full training, he'll be ready to go."
The Sounders (13-5-6, 45 points) sit in second place in Major League Soccer's Western Conference after winning four of their past six games. Seattle trails first-place Sporting Kansas City by one point heading into the teams' matchup Sunday in Kansas City, Kan.
