How can you possibly call yourself a doctor and post this crap? I seriously doubt you are. Its just a shtick for the forum. There are many tests that are done without an MRI. I am lucky enough that have coached football for a while and be on the sideline. Unfortunately, I have see our trainer use the Lachman test to determine if the ACL is torn. They can also use the Anterior Drawer test and the Pivot Shift test. I guarantee you at least one of these tests was done on Campbell on the field. They knew if he tore his ACL by the time he hit the sideline.
To determine a MCL sprain, the trainer uses the valgus stress test and the apprehension sign. Pressure is applied to the outside of the knee to see if the inside of the joint opens up (valgus laxity). The test is performed with the knee slightly flexed and fully extended to assess the ligament and the joint. While the test is being applied they look for a specific muscle reflex sign that indicates an MCL injury.
The extent and magnitude of the injury is determined by an MRI, but the Pats already know if its an ACL, MCL, or both. It just amazes me how a lowly sideline coach and trainer know these things, but someone bragging to be in medicine for 30 years doesn't. And we wonder what is wrong with the healthcare system? The Pats doctors/trainers are not speculating. They actually know. The MRI will tell them the extent. So when Vrabel said this morning on WEEI, "I wouldn’t imagine that Will’s going play in the game. I don’t think that will be something that will happen. That injury is going to probably be more than a week or two.” He was not speculating. If the ACL was torn, we would know already. Vrabel is indicating a sprain, and the extent will be clarified by later today for the team.
You show your idiocy with the arm comment. Go back to the J-E-T-S forum.
