Left tackle Trent Williams was still a bit sore Monday and his playing status remains day to day, Coach Mike Shanahan said after the Washington Redskins’ practice Monday.

Williams missed a second straight practice since suffering a bruised foot during the Redskins’ preseason opener last week. Williams did participate in a morning walk-through Monday.

Shanahan said he’s not sure how quickly Williams’s foot will improve. Williams said he felt “a lot better” and hoped to practice fully Tuesday. “If the coaches let me go,” he said, “I’m going.”

Running back Roy Helu also missed Monday’s practice, with tendinitis in his Achilles, and nose tackle Chris Neild hurt his left knee and is scheduled to undergo an MRI exam.

Rookie quarterback Kirk Cousins got significant work with the second-team offense during Monday’s practice. Shanahan called that part of the team’s normal practice field rotation for Cousins and veteran Rex Grossman, who are battling for the backup spot behind starter Robert Griffin III.

The Redskins’ projected starter at right tackle, Jammal Brown, has been sidelined all of training camp because of an ailing hip. Asked Monday if he thinks Brown will play for the team this season, Shanahan said he doesn’t know.

He said Brown remains quite sore, but the team plans to be patient, even while making contingency plans in case Brown doesn’t play.
