Can you actually SEE an Achilles tear??

Dr. Selene Parekh, Orthopaedic Surgeon, on Aaron Rodgers and his injury from Monday night against the Chicago Bears.

What is the impact of artificial surfaces on these types of injuries? What increases the rick of potential injuries? Are all Achilles tear the same? Is there an upper, lower, more severe type of tear? Dr. Parekh makes an assumption on what could be wrong with Aaron Rodgers. How much of his earlier calf strain could’ve contributed to this newer injury? Is this something that would’ve likely happen? Does Aaron Rodger’s age impact how quickly he returns? And will he be at a similar active level?
