Lions defensive end Ezekiel Ansah (groin) is listed as active Monday at Seattle, Tim Twentyman of the Lions' official site reports.
Ansah missed practice Thursday but turned in limited showings both Friday and Saturday, forecasting an appearance in Week 4. Through three games, he's supplemented a team-best two sacks with 12 tackles (10 solo).
Lions running back Joique Bell (ankle) didn't practice Thursday, and Dave Birkett of the Detroit Free Press noted that the running back isn't expected to play Sunday against the Cardinals.
The Lions haven't officially ruled out Bell for the Week 5 contest, but Birkett's report paves the way for Ameer Abdullah to head the backfield for a second week in a row. If Monday's loss to the Seahawks is any indication, Abdullah will earn most of the carries, while Theo Riddick serves in a pass-catching role.
Lions linebacker DeAndre Levy (hip) returned to practice Wednesday, The Detroit News reports.
Levy was forced to sit out of the Lions' Week 4 Monday night contest against the Seahawks with the hip injury, but he returned to practice Wednesday. There is a chance he takes the field Week 5, as the winless Lions play the Cardinals at home.
Wednesday marks Pettigrew's first practice since sustaining the hamstring injury Sept. 13, and he could be ready for the Lions' Week 5 matchup against the Cardinals.
Fellow tight end Eric Ebron (knee) is also banged up and expected to sit out a couple weeks, which would likely promote Pettigrew to the starting spot for the time being. Tim Wright would also likely see more snaps in Ebron's absence.
Bears cornerback Alan Ball accrued a season-high nine tackles and batted away a pass in Sunday's 26-0 loss to the Seahawks.
Though the Bears were beaten handily in Week 3, Ball was one of the team's more impressive performers defensively. In addition to showing activity in stopping the run, Ball was excellent during the Seahawks' final drive before halftime, denying a fade route intended for Jimmy Graham and defending Chris Matthews on another pass attempt.
Bears quarterback Jay Cutler (hamstring) was a limited participant in Wednesday's practice, the Chicago Sun-Times reports.
Cutler returned Sunday from a one-week absence due to a hamstring injury and didn't miss a beat, completing 28 of 43 passes for 281 yards, two touchdowns and one interception. Considering he was initially given a prognosis of at least two missed games, it isn't a surprise that his practice reps are limited to begin the week.
As long as the healing process continues unabated, he'll face a Chiefs secondary Sunday that has allowed 311 yards per game and 11 passing touchdowns to quarterbacks this season.
Jeffery (hamstring) was a limited practice participant Thursday, Adam Jahns of the Chicago Sun-Times reports.
With another limited showing in his back pocket, Jeffery has yet to show that he's in line to return for the first time since the season opener. The release of Friday's injury report will provide a good indication of his Week 5 availability, but if he returns, he could make a mark immediately against a Chiefs defense that has allowed 10 touchdowns to wideouts through four games.
Bears linebacker Shea McClellin recorded nine total tackles in Sunday's 48-23 loss to the Cardinals. For the second straight week, McClellin paced the Bears in stops, benefiting greatly from the Cardinals' decision to run the ball 28 times.
Royal (ankle) missed practice again Thursday, Adam Jahns of the Chicago Sun-Times reports.
Royal hasn't practiced this week due to an ankle injury, leaving only one day to show off his Week 5 viability. If he makes an appearance Sunday against the Chiefs, he may have to contend with Alshon Jeffery (hamstring) for targets for the first time since the season opener.
Sutton was expected to slide back to a bench role with Jeremiah Ratliff (ankle) returning from a three-game suspension, but both players are listed as questionable for Sunday, after logging limited practices throughout the week. If both suit up, Ratliff will probably get the start and play more snaps. Neither warrants IDP consideration.
