Chiefs’ Justin Houston, Jah Reid practice on Tuesday

Two starters who did not dress for the Chiefs’ 23-17 win over the Oakland Raiders on Sunday appear to be making progress.

Outside linebacker Justin Houston, who has a hyperextended knee, and right tackle Jah Reid, who has knee inflammation, each participated in the 20-minute portion of practice that was open to the media on Tuesday.

Houston, who has missed the Chiefs’ last five games, also practiced on Friday but did not play against the Raiders. Even still, Chiefs coach Andy Reid seemed optimistic about his potential availability in their wild-card playoff game Saturday against the Texans in Houston.

“He’s going to practice today, we’ll just take it day-by-day,” Reid said. “But I think he feels pretty good.”

Four other key Chiefs ― receiver Jeremy Maclin, outside linebacker Dee Ford, center Mitch Morse and safety Husain Abdullah― did not practice Tuesday.

Maclin sat because of a hip contusion sustained against the Raiders. He said after the game, however, that “there’s no way” he’d miss the Chiefs’ playoff opener.

Ford and Morse both missed practice because they are still undergoing concussion protocol, while Abdullah ― who has missed the Chiefs’ last five games ― missed practice for non-injury-related reasons. On Saturday, Abdullah posted on Twitter that his father had died.
