If Roy Williams does not play Sunday, which Cowboys WR will make the most of their opportunities?

Right now, the Cowboys are more of a .500 team than their 2-2 record suggests. Both of their hard-fought losses have come from two undefeated teams (the Giants and Broncos), while both wins have come at the expense of two teams (the Buccaneers and Panthers) that have yet to achieve their first victory.

When Dallas arrives at Arrowhead Stadium, it will face a Kansas City team that not only has yet to win this season, but did not win a game in the preseason; and in fact, has yet to taste victory since Week 13 of the '08 season. With a new head coach, new starting quarterback, and a new defensive scheme, the Chiefs are in a bit of a rebuilding process. Though, the same could be said of the Denver Broncos that have as many wins as the Chiefs have losses.

Looking forward to Sunday, some of the biggest concerns for the Cowboys are the injuries that affect some key starters. As we continue updating the injury updates, it looks like three players we expect to be ruled out for Sunday's game, will indeed be ruled out.

Cowboys head coach Wade Phillips all but ruled out three key players for Sunday's game against the Chiefs: WR Roy Williams (ribs), S Gerald Sensabaugh (thumb) and RB Felix Jones (knee).

"We're still going to wait and see, but it doesn't look good for the weekend for those guys," Phillips said. "You don't want to play with an injured player. Those guys were all injured and they hadn't gotten to the point right now it looks like they're going to be ready."

More Cowboys @ Chiefs after the jump.

Who would start in place of Williams? Miles Austin, this is your time to shine.

"Miles is working at it," Wade Phillips said. "He's going to keep working at it. When he gets his opportinities, he's tried to run the routes the way we want them run and worked at it. If he gets an opportunity we expect him to step up."

Missing Sensabaugh will cause the coaches to switch up their coverage schemes.

His spot will be taken by Patrick Watkins. Expect the Chiefs to look for tight end Sean Ryan early and often.

"You could see when he (Sensabaugh) went out, they hit a couple of passes on us to the tight end split out wide that we saw when Gerald wasnt' here,'' head coach Wade Phillips said of the Denver game. "You have to change things with what you do. Sometimes, you have to help a guy or play different techniques than we do with Gerald, but that's part of it.''

Not many of us really expected Felix Jones to play Sunday, but his being inactive looks to be confirmed.

According to a source, Dallas Cowboys running back Felix Jones will not play against the Kansas City Chiefs opting to rest the knee he injured against the Carolina Panthers in week 4.

Andre Gurode is practicing today, though. Phew!

Other than DE Wallace Gilberry, the Chiefs have full participation in practice from all their players.

When you're the quarterback of the Dallas Cowboys and you committ turnovers, expect criticism. Tony Romo knows that and has tapped his resources to help him deal with it.

Through it all, Romo says he's gained strength from recalling his conversations with Aikman and other former NFL quarterbacks. He said those chats taught him even the greats had tough times.

"It was a lot of hard work and effort and people beating you down," Romo said. "You have to have a stronger belief in yourself than the disbelief of others. That's part of the mental makeup you have to have to play this position and move forward."

The Dallas defenders have improved their game the last two weeks, but they feel they have to do more to help get those "W"s.

The Cowboys rank 26th in total defense, including 29th against the pass. They played better in the past two games after allowing 877 yards with no sacks and no turnovers in their first two games. But they still had unsightly marks. The Cowboys missed three tackles on Brandon Marshall’s 51-yard touchdown reception Sunday. The three-play, 73-yard drive gave the Broncos a 17-10 victory. So even though the defense the past two games allowed only 24 points — seven of them on a one-play, 9-yard drive following a Tony Romo fumble — and 608 yards while making six sacks and forcing four turnovers, the Cowboys — as a team — didn’t come out unblemished.

"We have high expectations; we have high standards," Cowboys inside linebacker Keith Brooking said. "We gave up 17 [points to Denver], and we didn’t win the damn game. So what does that tell you? That tells you it’s not enough. That’s the mentality we’ve got to have around here: Whatever it takes to get it done."

The Cowboys have given up too many big plays — 13 passing plays of more than 20 yards and 16 runs of more than 10 yards. Only seven teams have fewer sacks than the Cowboys’ six, and the NFL average is 8.3. Only one team — Pittsburgh — has fewer takeaways than the Cowboys’ four, and the NFL average is 6.3.

Dallas DE DeMarcus Ware. Even though Ware led the NFL in sacks last season with 20, his last sack came Dec. 20 against Baltimore.

Here is the NFL's video preview of the Cowboys @ Chiefs. After the preview, Sterling Sharpe on NFL Playbook gives mad love to Sam Hurd and thinks he will be key to Dallas grabbing a victory. Joe Theismann picks the Chiefs (surprised?), and Brian Baldinger says the Cowboys will win because of the defense's ability to limit third-down conversions.

Anthony Spencer will appeal the $5,000 fine from the league for grabbing Kyle Orton's facemask.

"I feel it [the fine] is unnecessary," Spencer said. "I tried to come down on the ball."

Andre Gurode likely will be fined, possibly the same amount, for a tripping penalty he had against the Broncos. He would not talk Thursday.

Kevin Hench at FOXSports moves Wade Phillips up past Jim Zorn for coaches on the hot seat.

All Wade Phillips has been able to deliver is two wins against two winless teams. Even if they beat the Chiefs this week, the Cowboys won't have a shot at their first victory over a team with a W under its belt until Oct. 25 against the Falcons.
