The Caitlin Clark-less Indiana Fever suffered another injury blow as Sydney Colson went down with an injury on Thursday against the Phoenix Mercury. The Fever have been shorthanded in the backcourt nearly all season, and Colson's injury has only made things worse. Indiana has also been quiet at the trade deadline, which means it won't be able to bring major reinforcements for Colson.The injury occurred in the first quarter, shortly after Colson entered the game. The veteran guard rushed for an offensive rebound on the wing, but slipped and was down for a lengthy period with her teammates surrounding her. Colson took a while to get back and was helped off the floor, limping, as she couldn't put any weight on her injured left leg.The Fever were again left without true point guards on the floor with Clark sidelined, too.According to the latest update via Fever's beat reporter, Scott Agness, Sydney Colson had been ruled out for the rest of the game, citing a left knee injury.Fever coach Stephanie White on Sydney Colson's injuryIndiana Fever coach Stephanie White provided an update on Sydney Colson's injury postgame. "We'll get some more evaluation when we get home tomorrow and see where we are," White said via CBSSports.com. For now, she revealed it was a left knee injury for the veteran guard. The Fever will provide her status once the evaluations are out. By the looks of it, Colson may have suffered a long-term injury. It was a non-contact blow, and she had a bad landing.The Fever's injury woes worsened as the game progressed, as Sydney Colson was joined by Aari McDonald in the locker room and Sophie Cunningham, too. While Cunningham's injury was minor, McDonald exited the game with a walking boot and crutches on her right foot. The Fever don't have their two true point guards in Clark and Colson.Their third option, McDonald, is also out with a potential long-term injury. The Fever may need to explore the free agent market again, where they picked up McDonald and Chloe Bibby amid their injuries this year.
