The team told NFL Media on Friday that starting right tackle Eric Fisher has been ruled out for Saturday's wild-card showdown against the Indianapolis Colts with the groin injury he suffered in Tuesday's practice.
The good news for the Chiefs is that Branden Albert is expected to return at left tackle after missing the past four weeks with a hyperextended knee. His replacement, Donald Stephenson, likely will shift to the right side against a Colts defense with 41 sacks on the year.
Fisher graded out as this season's 70th-ranked tackle, per Pro Football Focus, after Kansas City made him the top overall pick in last April's NFL Draft. Stephenson ranked at No. 64 after making seven starts for the Chiefs in 2013.
Here's the rest of Friday's injury news:
1. Also for Kansas City, while outside linebacker Justin Houston is probable and expected to start for the first time since dislocating his elbow before Thanksgiving, pass rusher Tamba Hali is questionable with a knee injury. Tough blow for a Chiefs defense with just 10 sacks since Week 12.
3. In Green Bay, Packers coach Mike McCarthy announced that rookie running back Eddie Lacy (ankle) looked good in Friday's practice and is probable for Sunday's game at frigid Lambeau Field. Packers receiver James Jones says the 49ers will see a "totally different" player after Lacy rushed for just 41 yards on 14 carries back in Week 1.
5. 49ers cornerback Carlos Rogers (hamstring) was on the field for Friday's practice without his jersey or helmet. He promised all week he'd be ready for Sunday, but told reporters after Friday's session: "I ran on it, but I don't know." Fellow cornerback Eric Wright also tweaked his hamstring in Thursday's session, but suited up Friday, according to the Santa Rosa Press Democrat. Wright was "moving all right," Comcast SportsNet Bay Area's Matt Maiocco noted.
The 49ers delivered the final verdict on Friday:
6. Panthers coach Ron Rivera told reporters Friday that Carolina plans to have receiver Steve Smith (knee), running back Jonathan Stewart (knee) and defensive tackle Colin Cole (calf) back at practice Wednesday.
8. The Bengals announced that cornerback Terence Newman is doubtful with a knee injury for Sunday's playoff tilt with the San Diego Chargers. A laundry list of Cincy players are questionable, including defensive end Wallace Gilberry (concussion) and tight ends Tyler Eifert (neck) and Jermaine Gresham (hamstring), who both practiced fully Friday.
9. For the Chargers, defensive tackle Sean Lissemore (shoulder) and receiver Eddie Royal (toe) are questionable. Running back Ryan Mathews practiced for the first time all week (ankle) and is listed as probable.
