Paul Arriola, who is set to open the 2021 season with a rookie season with the D.C. United team, confirmed Friday that he’s slated to undergo arthroscopic surgery on his left knee later this month.

“I do have a procedure coming up to remove some debris and clean up my left knee,” Arriola told WEEI.com. “I’m not going to worry about if it’s going to affect me or not at this point.”

Arriola, 31, had surgery on both of his knees in 2008.

Arriola told WEEI that the repair will take about two weeks. Once the scope is complete, he said, he will undergo at least a week of rehab.

He did not mention a timeline for his return.

Arriola says he has some discomfort and swelling, but he does not know the exact nature of the injury or how it occurred.

Arriola’s left ACL was twice surgically repaired at the University of North Carolina (the first time in 2002, the second in 2006).

He’s expected to join the United on its 10-game tour of Brazil in March. He will then sign a contract with D.C. United that will allow him to play in the English Premier League with Reading during the MLS season.

Arriola signed a multi-year deal with the Sky Blues at the beginning of the month, according to MLS.

Arriola has scored 48 goals in 104 career MLS matches. Arriola joined the D.C. United team in 2009 after spending four seasons with Aalborg, which is now coached by ex-United and Washington Mystics coach Billie Jo Larsen-Ohlsen. He was the 2007 US Soccer Collegiate Player of the Year.

Arriola entered MLS in 2009 and posted 12 goals in 68 games for United. Arriola led the team in goals and points as a rookie, 2012, with 12 goals and 14 points in 31 games. Arriola had 30 goals and 22 assists in 80 career MLS games. He is tied for eighth all-time in MLS with 36 goals.
