Vikings coach Kevin O'Connell reacts to Rondale Moore's injury on his first play of the preseason after he missed all of 2024 with an injury. (0:45)Open Extended ReactionsMINNEAPOLIS -- Minnesota Vikings wide receiver Rondale Moore suffered a "pretty significant" injury to his left knee against the Houston Texans on Saturday, coach Kevin O'Connell said. The injury came on Moore's first play after returning from a major injury last season to his right knee. O'Connell did not provide a specific diagnosis, pointing to an MRI test that will be conducted Sunday, but called the situation "heartbreaking." Moore has struggled to stay healthy since the Arizona Cardinals made him a second-round draft pick in 2021.
