Four Vikings players remained sidelined during today's practice.

A trio of starters in safety Harrison Smith, right guard Brandon Fusco and cornerback Trae Waynes did not practice. Neither did 2016 first-round draft pick Laquon Treadwell, a reserve wide receiver.

Smith has not practiced since the loss to the Cowboys on Dec. 1. He is dealing with an ankle injury and is in danger of missing his second straight game, though there is still some hope he could play Sunday.

Fusco and Waynes both suffered concussions in Jacksonville.

Treadwell injured his ankle early in that win over the Jaguars.

Defensive end Justin Trattou also missed practice with a "forehead" injury after a fluky collision with wideout Adam Thielen after yesterday's practice.

There appears to be positive news, though, regarding starting center Joe Berger, who has missed two games with the concussion he suffered on Nov. 24. He has now suited up for back-to-back practices.

Running back Adrian Peterson was practicing again, by the way. Ditto for quarterback Sam Bradford, who is dealing with a shoulder injury.
