Unlike last week's nfl.com transaction miscue surrounding Scott McKillop, the 49ers have apparently confirmed a separate roster move today as they have reportedly waived linebacker Thaddeus Gibson. The beat writers are tweeting it out at this point while we wait for the official roster email.
When the 49ers released a preliminary preseason depth chart, Gibson was listed as third string ROLB behind Parys Haralson and Aldon Smith. The addition of Antwan Applewhite put Gibson in a tough position, so the waiving is not shocking. I am surprised by the timing since roster cut downs are still a ways off. Gibson traveled to New Orleans and was dressed but saw no action.
As to the previous McKillop error, apparently the mistake was related to his injury a year ago, with the subsequent roster move also occurring on August 11. A year later and somehow their was a mix-up at nfl.com. Such is life.
