Are the USC Trojans liable for the injuries sustained by former RB Stafon Johnson?

The lawsuit says "Yanchar's negligent, careless and reckless act and omission, in striking the bar with his body, was something that Mr. Johnson was not expecting to occur and he was therefore unprepared for the bar to be knocked off balance." ESPN reports, Johnson seeks "unspecified damages for medical-related expenses, pain and suffering and loss of future earnings exceeding $25,000, the lawsuit alleges that Yanchar was distracted and not paying attention to Johnson at the time of the incident and thus 'failed to take notice that, as the bar was being lifted from the rack, Johnson was not then ready to take hold of and lift the bar.'"

Johnson is currently in the NFL and seems to have fully recovered. In my opinion, this lawsuit is unnecessary. No matter how his lawyer spins it, this was an accident. I know in our legal system accidents can result in a financially lucrative lawsuit, but it is wrong. USC did not cause nor would it ever want such an injury to occur to one of its great athletes. This was a tragic accident, and that's how I think it should be treated.
