FRISCO, Texas -- Pro Bowl left tackle Tyron Smith will end the season on injured reserve because of a sprained knee after fighting through back, groin and hip injuries from the early part of training camp.

The Cowboys will place Smith and cornerback Orlando Scandrick on injured reserve and call up wide receiver Lance Lenoir and offensive tackle Kadeem Edwards from the practice squad.

Smith sprained the lateral collateral ligament in his right knee in the Cowboys’ Week 15 win against the Oakland Raiders. He attempted to play last week against the Seattle Seahawks but lasted just the first three snaps of the game.

As of now, the plan is for Smith to not need surgery as rest should help him heal, but that will be re-evaluated in the coming weeks. He is likely to skip the Pro Bowl because of the injury as well.

He and Scandrick, who missed the previous three games with two transverse process fractures in his back, were not going to play Sunday against the Philadelphia Eagles.

The call ups of Lenoir and Edwards are rewards of sorts for their work during the season since it is not likely either will be active this week. They will go from earning $7,200 this week for being on the practice squad to $27,352 for being on the active roster. They will sign deals through 2019.
