I buy it. Wright has been right about the Tyson Jackson and Dexter McCluster injuries. No reason to believe he is wrong this time. It appears as though he has a fairly reliable source on injury news at Arrowhead.
Depending on the severity of the concussion, Moeaki could be out next week. The NFL has been much stricter with head trauma this year and most players who have been diagnosed with a concussion have missed the following week.
