MINNEAPOLIS -- The Minnesota Vikings' new stadium is quickly rising on the east end of downtown Minneapolis, but construction workers still have plenty of time to tend to the little things -- like erasing a pro-Green Bay Packers message that Wisconsin Gov. Scott Walker tried to slip into the stadium.

While making a campaign visit to River Steel in West Salem, Wisconsin, Walker signed a steel beam that was being fabricated for the Vikings' stadium, also writing "Go Packers" on the beam, according to the New York Times.

However, when River Steel sent the beam to the main steel fabricator -- LeJeune Steel in Minneapolis -- the message was erased.

"Governor Walker did sign a piece of steel that was in a fabrication shop in Wisconsin, but his signature and whatever else he wrote has been removed from that piece of steel," Mortenson Construction senior vice president John Wood told Minnesota Public Radio.

Walker had boasted about his hijinks during a campaign appearance in Schofield, Wisconsin, on Friday.

The $1 billion stadium is slated to open in time for the 2016 season, and will host the Super Bowl in 2018.
