The Kansas City Chiefs kicked off their minicamp on Tuesday.

Here's what you need to know:

Nuts and Bolts * *

• The Chiefs held their first of three days of practice at their mandatory minicamp
• Just like OTAs, players are not allowed to wear pads
• After a walkthrough earlier in the day, the players spent just over two hours practicing outside in the afternoon on Tuesday
• DL Dontari Poe returned to practice for the first time in several days
• WR Albert Wilson once again did not practice as he's dealing with a hamstring issue
• Rookies Marcus Peters and Steve Nelson had their first practice after missing OTAs
• Jamaal Charles, Tamba Hali, Jeremy Maclin, Steve Nelson and Marcus Peters spoke to the media after the walkthrough earlier in the day

Plays of the Day * *

Early in team drills, receiver Jeremy Maclin caught a contested pass across the middle from quarterback Alex Smith. Maclin snagged the high pass out of the air with a defender on his back, which gave the offense a nice gain down the field.

But the best pass of the day came from Smith down the left sideline on a vertical route to rookie receiver Chris Conley. Conley had a step on the defender and Smith led him perfectly down the field as the pass got over the cornerback and in front of the safety.

Once again, Kenny Cook, the rookie receiver from Gardner Webb, made another nice catch down the field on a pass from Aaron Murray. The ball was thrown over the outside shoulder of Cook, who tracked it from over the inside shoulder all the way around and caught the ball right on the tips of his fingers before securing it as he went to the ground. Cook's name has been consistent in the Plays of the Day sections of these articles for a while now.

Fullback Anthony Sherman also made a nice juggling catch down the middle of the field on a pass down the seam from Alex Smith. Sherman was covered well by linebacker Derrick Johnson and showed some nice concentration to secure the pass as it bounced around several times before landing in Sherman's hands as he laid on the ground.  

The best catch of the day came from receiver Fred Williams, who caught a pass deep down the left sideline from quarterback Chase Daniel. This play would have been a top-10 highlight on any given week during the regular season. Williams tracked the ball over his outside shoulder near the sideline and was able to win the 50-50 battle with the defender. It may be the best catch of the Chiefs' offseason thus far.

Here are a few clips of Tuesday's practice:

Player Spotlight – Marcus Peters * *

The Chiefs got their first look at their first-round pick, cornerback Marcus Peters, running around the field with his veteran teammates on Tuesday afternoon on the first day of mandatory minicamp.

Due to NFL rules, both Peters and fellow rookie Steve Nelson weren't able to participate in the ten OTA practices over the past three weeks.

Despite missing that time, Peters said he's ready to go.

"I just had to miss a few weeks, but I don't feel behind at all," he said.

One of the guys Peters was in contact with throughout this downtime was assistant defensive backs coach Al Harris, who Peters is looking forward to working with on a daily basis.

"He's going to be a mentor to me," Peters explained. "I'm going to sit in his back pocket and learn as much as possible."

With just three days to practice before having several weeks off until the start of training camp, Peters knows he has to take advantage of all the time he can on the field.

"It's time to go now," Peters said. "Let's get this work in for these three days that we're here and once we come back for training camp—it's high expectations.

"I put high expectations on myself. I'm wanting to come in and make an impact for this team. That's with any way I can—that's special teams and everything.

"I'm just taking my reps and having fun with it." 

Peters spent time with both the first and second-team defenses on Tuesday and is one of just three rookie cornerbacks on the Chiefs' roster right now, along with Steve Nelson and Justin Cox.

"It's been a warm welcome," Peters explained of his veteran teammates. "It's going to be a wonderful group back there. Like they say, I'm just another piece to the puzzle. We are all here to get a job done and that's to win football games for the Chiefs.

"But it feels real good to be back out here."
