Funnyman Tracy Morgan has fired back at allegations he's partly responsible for the injuries he suffered during a car crash earlier this year (Jun14).

Lawyers representing supermarket chain Walmart, whose driver caused the accident in New Jersey, suggested Morgan should have been wearing a seatbelt at the time of the crash as part of their defence.

The claim has left Morgan, who lost his mentor and best friend Jimmy MCNair in the pile-up, fuming and he has responded.

The comic says, "I can’t believe Walmart is blaming me for an accident that they caused. My friends and I were doing nothing wrong."

He adds, "I want to thank my fans for sticking with me during this difficult time. I love you all. I’m fighting hard every day to get back."

Morgan and the other survivors of the crash are suing Walmart, accusing bosses of negligence and alleging company executives should have known driver Kevin Roper had been awake for more than 24 hours and that his drive from his home in Georgia to work in Delaware was "unreasonable".

Roper stands accused causing the multi-vehicle accident after allegedly falling asleep at the wheel of his truck.
