The Raiders were expected to make a change at right tackle. Less than two hours before taking on the Colts, that change was announced as Austin Howard is inactive for the day.
Howard has started 10 of the 11 games he has played in this season. Menelik Watson is expected to take over the starting job.
Oakland will also be without Connor Cook, Antonio Hamilton, Karl Joseph, Denver Kirkland, Stacy McGee and Branden Jackson.
After visiting the Titans, Saints and Rams, free agent defensive tackle Ndamukong Suh will make a stop in the East Bay.
Recently released by the Dolphins, Suh will visit with the Raiders on Wednesday, according to ESPN.
The former No. 2 overall pick made it through just three seasons of a six-year, $114 million deal he signed with Miami prior to the 2015 season.
The 31-year-old Portland, Oregon native last made the Pro Bowl in 2016 and was last earned First-Team All Pro honors in 2014.
In 16 games with the Dolphins last season, Suh recorded 4.5 sacks and 48 combined tackles.
As the Raiders overhaul their receiving corps, they are meeting with a versatile veteran on Tuesday.
Eric Decker, who spent the 2017 season with the Titans, is visiting the Raiders, according to The Athletic and ESPN.
A third-round pick out of Minnesota in 2010, the 31-year-old Decker spent the first four seasons of his career with the Broncos. He put up huge numbers in 2012 and 2013 with 2,352 receiving yards and 24 total touchdowns over those two seasons.
He turned his success with the Broncos into a five-year, $36 million contract with the Jets. He lived up to the contract the first two seasons, but after playing in just three games in 2016, the Jets released him.
So far this offseason, the Raiders have added veteran Jordy Nelson and Griff Whalen while releasing Michael Crabtree and trading Cordarrelle Patterson to New England.
