Antonio Brown has not done much in Raiders training camp, beginning it on their active/NFI list and having missed almost all of his new team’s sessions thus far. An offseason foot problem, one recently labeled “very minor” has shelved the 31-year-old superstar. Brown is now set to visit a foot specialist on Saturday, Vic Tafur of The Athletic tweets. Jon Gruden said Friday he’s disappointed Brown has not been able to do much in camp, and while The Athletic’s Lindsay Jones tweets Brown is only dealing with foot blisters, a specialist visit is not a great sign to start Brown’s Oakland tenure. Frustration is mounting on both sides, but this is still being viewed a minor malady, per the Las Vegas Review-Journal’s Michael Gehlken (Twitter links). Brown has missed six of seven Raider camp workouts and has not participated in a full session yet.

Here is the latest from the AFC West, shifting first to the Broncos’ most recent skill-position addition:

• Theo Riddick ended up choosing the Broncos as his second NFL team. In an era that has seen running back value plunge considerably, Riddick did relatively well. His Broncos deal is for one year and $2.5MM, Mike Klis of 9News tweets. With a $1MM guarantee, it’s a good bet Riddick will join Phillip Lindsay and Royce Freeman in Denver’s Week 1 backfield. Incentives being met would spike this pact’s value to $3.3MM, Klis adds. The Broncos were fairly well-stocked at running back, though injuries have sidelined both Lindsay and Freeman for stretches to start their careers. Riddick would also stand to help the Broncos in the slot.
• Continuing on the subject of Broncos roles, it is Bradley Chubb, not Von Miller, who is stationed in the Khalil Mack outside linebacker position in Vic Fangio‘s defense, Charles Robinson of Yahoo.com tweets. While likely to be viewed as Denver’s No. 2 pass rusher throughout Miller’s prime, Chubb is coming off a 12-sack rookie season.
• The Chiefs are moving cornerback Tremon Smith to running back, as B.J. Kissel of the team’s official website tweets. Smith only played 82 defensive snaps as a rookie, serving primarily as a kick returner. The 2018 sixth-round pick joins Damien Williams, Carlos Hyde, 2018 UDFA Darrel Williams and 2019 sixth-rounder Darwin Thompson. Given Smith’s work as a return man, he seems a fairly safe bet to make his way back to Kansas City’s 53-man roster.
