Philadelphia Eagles right tackle Lane Johnson will miss Sunday's game against the Seattle Seahawks due to a concussion, the team announced Friday.
Rookie offensive tackle Andre Dillard, who has never played right tackle at any level, will take over. Dillard started three games earlier in the season in place of left tackle Jason Peters.
Additionally, running back Jordan Howard (shoulder) and wide receivers Alshon Jeffery (ankle) and Nelson Agholor (knee) are listed as questionable.
Howard, who sat out against the New England Patriots last week due to a stinger, needs to be cleared for contact before he can return to the lineup.
Jeffery suffered his injury in a Week 9 win over the Chicago Bears and also missed last Sunday's loss despite resting in the Eagles' intervening bye week.
