Garner was waived by the Broncos on Thursday after undergoing an appendectomy on Wednesday, Mike Kils of 9News reports.
Garner was competing for a spot at the bottom of the depth chart for the Broncos, and his surgery couldn't have come at a worse time. It can take up to a month to recover from an appendectomy, which would be enough to keep the undrafted rookie out nearly all of camp and is likely the reason Denver waived him.
