The Kansas City Chiefs expect wide receiver Jeremy Maclin to pass concussion protocol and play Sunday against the Pittsburgh Steelers, according to ESPN's Ed Werder.

The report indicates Maclin will likely rejoin the team for practice Friday. It's a positive sign after he missed the first two days of practice this week and appeared to be in danger of sitting out Week 7.

Maclin was diagnosed with a concussion following Sunday's loss to the Minnesota Vikings. The Chiefs' top receiver was injured after being tackled by Vikings cornerback Captain Munnerlyn, with his heading crashing into the turf.

After signing with the Chiefs in the offseason, Maclin quickly emerged as their No. 1 receiving threat, amassing 39 receptions, 531 yards, and one touchdown.
