Sami Whitcomb injury update: Mercury guard out to start season with knee injury

PHOENIX *—*The Phoenix Mercury will tip off the 2026 WNBA season without an experienced guard that was pivotal in the team's run to the WNBA Finals last year.

Sami Whitcomb is expected to miss at least four to six weeks as she's set to undergo an arthroscopy Thursday to remove a loose body in her left knee, the team announced on Wednesday. Whitcomb revealed that the injury happened after she came down on a rebound attempt and "felt something" in her knee during practice.

"It was unusual for me. So I just subbed myself off and went and saw the doctor," Whitcomb recalled Wednesday.

Mercury head coach Nate Tibbetts said he witnessed the whole thing go down and instantly knew something was wrong after making eye contact with Whitcomb upon landing.

"I think we're the only two that kind of saw the situation that happened in practice. I was standing under a basket. (Whitcomb) kind of went for a rebound and landed and she just kind of made a face," Tibbetts recalled Wednesday during the Mercury's media day. "I looked at her and, 'Hey, you all right?' She's like, 'I don't know.'"

Whitcomb averaged 9.1 points, 2.6 rebounds and 2.5 assists in her first season in Phoenix after two stints with the Seattle Storm and two seasons with the .
