Alex Smith will not feature for the Washington Football Team against the Seattle Seahawks in Week 15, with Dwayne Haskins set to take his place at quarterback.

Smith made a remarkable return to the field in October having suffered a life-threatening leg injury in 2018 that required 17 surgeries.

He became the starter in Week 10 after Kyle Allen was ruled out for the season and, after suffering defeat to the Detroit Lions in that encounter, has been the quarterback for four successive wins.

However, Smith has not practiced this week because of a calf strain sustained in the 23-15 win over the San Francisco 49ers last Sunday.

His absence means Haskins, who replaced Smith in the second half against San Francisco, will start for the first time since Week 4.

Rookie running back Antonio Gibson is also doubtful to face the Seahawks with turf toe. Gibson missed the defeat of the 49ers.

Washington lead the NFC East with a 6-7 record, though Ron Rivera's team have leaned predominantly on their defense during their recent winning streak.

Indeed, Washington did not score an offensive touchdown against the 49ers and are averaging only 4.9 yards per offensive play.
