C Mitch Morse missed his third straight game Sunday with a sprained foot and did not practice Wednesday. Backup C Zach Fulton expects to continue starting in his place until Morse is healthy.

WR Chris Conley will miss the rest of the season after it was confirmed he ruptured his Achilles tendon Sunday night against Houston. Conley went down after recovering an onside kick late in the ball game. The Chiefs have yet to place Conley on injured reserve or make a roster move replacing him. He expects to undergo season-ending surgery soon.

RG Laurent Duvernay-Tardif remains out of practice with a sprained knee sustained in Week 4 against Washington, and appears likely to sit this week as well. OL Cameron Erving drew the surprise start in his place last week, and appeared to perform well enough to earn continued playing time in Duvernay-Tardif's absence.

TE Travis Kelce remains in the league's concussion protocol following a helmet-to-helmet he received during Sunday's game against Houston. Kelce briefly returned to the game after being cleared by the league's unaffiliated neurological consultant but experienced memory issues during halftime and left the game for good. Head coach Andy Reid said he feels good but remains unsure of his availability against Pittsburgh. Kelce did attend Wednesday's practice while watching from the sidelines.

DT Bennie Logan was limited in practice Wednesday. The team continues providing additional rest for Logan, who has battled knee inflammation since training camp. He is not expected to miss any game time.

S Steven Terrell sustained a concussion on the opening kickoff of Sunday's game after taking a knee to the helmet. There is no timetable on the return of the backup safety, who contributes primarily on special teams.

WR Albert Wilson sat out practice Wednesday after spraining a knee Sunday night against Houston. Head coach Andy Reid indicated Wilson continues improving day by day and expects to play against Pittsburgh this week.
