Rodman and Monterrey’s Daniela Monroy competed over a ball along the touchline in the 37th minute, with the California native appearing to suffer the injury as she attempted to poke the ball loose.
Rodman stayed down before signaling that she needed help from the trainers, and looked to be in serious pain as she was attended to. Spirit staff carried her off the pitch at Audi Field, with Rodman placing no weight on her right leg. Washington would eventually substitute her, sending Brittany Ratcliffe on in the 41st minute.
During the halftime break, Rodman headed from the Spirit bench to the locker room on crutches.
‘We need to wait until tomorrow,’ Spirit coach Adrián González told reporters after the match. ‘She’s going to get scanned tomorrow, and we will have more information.’
The injury comes at a difficult time for Rodman and the USWNT. Earlier on Wednesday, she received her first call-up since April, having overcome a long-term battle with a persistent back injury over the summer.
Since returning to the pitch for the Spirit, Rodman has been in imperious form. The 23-year-old was named the NWSL Player of the Month in September after scoring three times and adding two assists across four games. Rodman scored again for Washington this past Saturday in a 1-1 road draw against the North Carolina Courage.
