KANSAS CITY, Mo. — The beleaguered offense of the Kansas City Chiefs took another hit on Wednesday when right guard Mike Goff went on injured reserve.

That means the Chiefs (1-7) and their struggling ground game will be without their starting right guard and their most accomplished running back, Larry Johnson, against Oakland on Sunday.
Johnson, just 75 yards away from breaking the team rushing record, was released on Monday after being suspended for making inappropriate posts on his Twitter account.
Averaging fewer than 97 yards, the Chiefs’ rushing game will depend now on Jamaal Charles and Kolby Smith. Both offer more speed and a better chance of breaking a long play than Johnson, a two-time Pro Bowler who was averaging only 2.7 yards per carry this year behind spotty blocking.
Smith saw his first action last week in a year and had 17 yards on four carries. The Chiefs were being careful since he was coming off knee surgery.
Smith might even start against the Raiders.
“He’s worked real hard. I wouldn’t put it past him,” said coach Todd Haley. “I’m still trying to keep it within reason and not have the expectations too high and understand really what the situation is. But I would say Kolby Smith’s the type of guy who could surprise. I wouldn’t say its out of reason.”
Goff, a 12-year veteran, had started seven games for the Chiefs (1-7) before going down with a shoulder injury. He will probably be replaced by Andy Alleman, a three-year veteran who was acquired in a trade in August from Miami. Another possibility is Ikechuku Ndukwe, who has been backing up right tackle Ryan O’Callaghan.
“Mike obviously was an important piece to us that we signed in the offseason to help a lot of these young guys figure out how to do it,” said Haley. “It’s disappointing that his season is over. But injuries are a part of this game.”
Alleman stepped in when Goff was injured last week against Jacksonville.
“He missed a couple of plays there but he fought back and finished the game strong and did some good things,” Haley said. “We’ll have to carry on. Injuries are a part of the game. Guys have to step in and get the job done.”
The Chiefs also signed linebacker Justin Rogers on Wednesday. He appeared in 31 games the past two seasons with the Dallas Cowboys and made three tackles.
