TEMPE, Ariz. - Two Arizona Cardinals starters, running back Andre Ellington and right guard Paul Fanaika, have been ruled out of Sunday's game against the Kansas City Chiefs.

Ellington sustained a hip pointer in last Sunday's loss at Atlanta. He already had been dealing with soreness in the other hip and, most significantly, a partially torn tendon in his foot.

Second-year pro Stepfan Taylor will start in Ellington's place, with rookie Marion Grice backing him up.

One player who won't be in the mix is running back Michael Bush. He was released by the team Friday afternoon after being signed last week as potentially the power back the team has lacked.

Fanaika has a high ankle sprain. The injury will clear the way for Jonathan Cooper, last year's first-round draft pick, to make his first pro start. Cooper will start at left guard, with Ted Larsen moving to right guard.

Cooper, the seventh overall pick in the 2013 draft, missed all of last season with a broken leg and was beat out for the job by Larsen this year. He did played most of last weekend's game after Fanaika was hurt.

"He's had a real good week," Arizona coach Bruce Arians said of Cooper. "Last week helped him, having three-quarters of the game, so he's more than ready."

Wide receiver Larry Fitzgerald was listed as questionable on Friday after going through a full practice for the first time since bruising his left knee against Detroit on Nov. 16. He had been limited in practice the rest of this week. Fitzgerald had missed the last two games, both of them losses.

"He's practiced all week," Arians said. "He's gotten better each day, but it's still not 100 per cent."

Both Fitzgerald and starting inside linebacker Larry Foote (foot injury) will be game-time decisions, Arians said. But he said left tackle Jared Veldheer, who sprained his ankle in last week's game, should be ready to go even though he's listed as questionable.

The Cardinals activated outside linebacker Matt Shaughnessy. He had been on the injured/eligible to return list after he injured his right knee and was not allowed under the NFL rule to return until after eight games.

The team also released tight end Matthew Mulligan and, for the second time, elevated running back Kerwynn Williams from the practice squad.
