The Bears will host the Chiefs in a preseason game Saturday at Soldier Field. Here are four players who should have an excellent chance to prove they deserve a role with the team:

Center Cornelius Edison

With center Hroniss Grasu out for the season with a torn ACL and right guard Kyle Long currently sidelined with a sore shoulder, Edison figures to get a long look against the Chiefs.

The 6-3, 309-pounder has performed well in training camp and the first two preseason games and will look to continue his momentum Saturday versus Kansas City. The Portland State product spent the final five weeks of his rookie season on the Bears practice squad last year after recovering from a torn ACL he suffered during a pre-draft workout.

"Going through that injury wasn't the easiest thing," Edison said. "It was definitely hard to swallow. I was not expecting that to happen. But it happened and I worked through it. I had to get my leg strength back and [deal with] the mental side of knowing that I tore my ACL."

Greg Scruggs is an aggressive blocker with raw receiving skills.

Quarterback Jay Cutler has been impressed with Edison, saying this week: "He's a good kid. He's trying to do everything we ask him to do. It's different, I think, stepping into that huddle with so many guys up there and then you have to be the voice for those five."

Tight end Greg Scruggs

The competition for backup roles at tight end behind starter Zach Miller continues Saturday, with Scruggs hoping to show that the same toughness and tenacity he utilized as a defensive end prior to this year will translate to the other side of the ball.

Scruggs is an aggressive blocker with raw receiving skills, never having caught a pass in an organized football game. Prior to moving to tight end in May, Scruggs' only experience at the position came during spring ball and preseason camp when he attended Louisville.

With Miller continuing to recover from a concussion, veteran Tony Moeaki was stepping up before hurting his hamstring last week against the Patriots. Rob Housler has also made a push for more playing time, catching a two-point conversion pass from Cutler and turning a short Brian Hoyer throw into a 52-yard reception versus New England.

Cornerback Jacoby Glenn

The Bears are looking for a cornerback to team with veteran Tracy Porter while Kyle Fuller recovers from arthroscopic knee surgery, and Jacoby Glenn could be that individual. The second-year pro from Central Florida consistently broke up passes during training camp, but he suffered a concussion against the Patriots that sidelined him for a few days.

Now healthy, Glenn is eager to make the most of his playing time against the Chiefs, saying: "It's a great opportunity to get out and learn, compete with older guys and better guys and really help me use my ability to be great."

The 6-foot, 185-pounder is undersized, even for a cornerback, and must prove that he can provide run support, play physical on special teams and remain healthy.

Safety DeAndre Houston-Carson

Another unproven young player who missed some time with an injury, Houston-Carson is now healthy after hurting his neck in the preseason opener and eager to show that he can make plays on both defense and special teams in the NFL.

"This is another good opportunity to get better, put some good stuff on tape and do it full speed," Houston-Carson said. "It's different doing it in a game than doing it in practice."

After playing cornerback his first three seasons at William and Mary, Houston-Carson moved to safety as a senior and responded by recording a team-high 109 tackles and four interceptions, returning one 94 yards for a touchdown. He also excelled on special teams, blocking nine kicks during his college career.

Asked what he wants to show coaches Saturday, Houston-Carson said: "The main thing is just that I'm dependable, I know my job and I'm where I'm supposed to be. I think if I do that, I'll make plays."
