Raiders G Jackson leaves practice on cart

Oakland Raiders guard Gabe Jackson left Thursday's joint practice with the Los Angeles Rams on a cart with an apparent leg injury. The entire Raiders offensive line gathered around the 28-year-old veteran before he was wheeled off for further evaluation.

The nature of the injury was not immediately clear, but multiple reports said the starting right guard was unable to put pressure on his leg. Head coach Jon Gruden said the team was "concerned," but declined to speculate about the injury. Jackson has started 72 of his 73 games over the last five seasons since Oakland selected him in the third round of the 2014 NFL Draft.

He signed a five-year, $56 million extension after the 2017 season.
