She was taken off on a stretcher after about 25 minutes on the court.
A gut-wrenching scene unfolded on Court 17 at Wimbledon on Thursday as Bethanie Mattek-Sands injured her knee.
Mattek-Sands had won the first set 6-4 and lost the second on a tie-break moments before the fall occurred.
And opponent Cirstea, who was first on the spot to help her stricken friend, felt the American wildcard entrant was left too long crying in pain. I panicked a little bit as well and called for help but no one was coming and I tried to comfort her as much as I could but you could feel the pain.
According to ESPN, the injury not only forced Mattek-Sands to withdraw from the singles tournament, but will likely do the same for the doubles, where Mattek-Sands and her partner, Lucie Safarova, were expected to compete for their fourth straight Grand Slam title. I went over. I saw her knee out.
Medics and trainers came over to help Mattek-Sands - who's had several injuries to the same knee throughout her pro career - and stretchered her off the court 15 minutes later. "These painkillers are not working", she reportedly said. It took a while until the medical team was there - for a long time it was just me, her husband and my physio. "Sorana, help me. Sorana, help me, '" Cirstea said. In this kind of moment when she was screaming so loud, you watch the knee, it was a very uncomfortable moment. I think was tough because she was stuck on this, Sorana, help me, Sorana, help me.
Mattek-Sands is one of the most experienced figures on the WTA Tour having turned professional 18 years ago.
Cirstea, who had dropped the first set 4-6 but took the second 7-6 (4), was declared the victor of the second round match.
