There has been an injury trend that is hard to miss for the first month of the 2021 season. May has arrived and the injuries just keep piling up. There have been a lot of muscle/tendon sprains and strains to start the season. These injuries include oblique, groin, hamstring, and back injuries. Not all of the injuries are the same for each player and should be treated and evaluated on a case-by-case basis. They should not be lumped together. Key words to listen for while getting updates on these injuries include what grade the strain is to determine how severe it is. That is the best way to help evaluate how long that player will be out for.
Baseball has seen the rate of injury continue to rise over the past few years. In fantasy, if someone is not in the medical field, it is hard to gauge how long a player will be out and whether they need to be replaced in a lineup. Sometimes this could mean playing a dead roster spot and losing the opportunity to have a full week of stats. Watching a play and watching the mechanism of injury can say a lot about the type of injury that has been sustained.
I am a practicing physician's assistant in the state of New York in the fields of orthopedics and physical medicine/pain management. I have been treating patients with the same type of injuries that have been affecting athletes in a private practice setting for the past 16 years. Having this base of knowledge, it is easier to “predict” what the injury could be and how much time a player may miss. During the course of the season, I will continue to provide the latest injury updates with diagnoses and discuss the extent of injury and how long the player will be out. I will also be listing the “next man up” when it comes to playing time if the player will be out.
