Nuts and Bolts of Tuesday's practice:

• Chiefs held their fourth of 10 OTA practices allowed by NFL rules
• Linebacker Derrick Johnson sat out with knee inflammation, not considered serious
• Defensive lineman Dontari Poe left practice early with back injury, also not considered serious
• Team practiced for just over two hours. Weather was overcast
• After practice, Alex Smith, Albert Wilson, Sean Smith and De'Anthony Thomas spoke to the media

Positional Spotlight – Defensive Line While Dontari Poe may have left practice early, the rest of the defensive lineman got plenty of work done on Tuesday afternoon. Mike DeVito stepped in at Poe's spot during 11-on-11 work.

Here are a few clips of what practice looked like today for the Chiefs.

Top plays from Tuesday's practice

Early in 7-on-7 work, cornerback Marcus Cooper had a great pass breakup down the field on a pass intended for Jason Avant. Cooper extended up with one hand as he left his feet to get a hand on the ball.

On a couple of occasions during practice on Tuesday, Alex Smith and Jeremy Maclin hooked up for a nice throw-and-catch down the field. On one play in particular, Smith found Maclin on a deep post and the ball was placed perfectly into a window between three defenders.

Cornerback Sean Smith had another interception on Tuesday and after practice, he said that turnovers are something the defensive players have been preaching to each other all offseason. Smith made a nice play on the ball on an attempted out route to Albert Wilson.

Smith beat Wilson to the outside and dove to make the catch, which Alex Smith jokingly told Sean Smith after practice was trapped. Sean obviously disagreed, but there was no replay on the non-existent jumbotron.

Rookie tight end James O' Shaughnessy had another nice day on Tuesday with a couple of good catches across the middle. On one play in particular, O'Shaughnessy had a double move that created some space for him down the field and Alex Smith hit him perfectly in stride.

Albert Wilson had a nice catch across the middle during 11-on-11 work. He snagged the ball right out of the air while in traffic on what would have been a good catch-and-throw. It was definitely one of the moments in practice when everybody raised his or her eyebrows a little bit.

Player Spotlight – Receiver Albert Wilson

Towards the end of last season, Albert Wilson became a reliable target for Alex Smith on the outside.

In the final four games of the year, the undrafted rookie from Georgia State had 12 receptions for 209 yards.

That's good for an average of 17.4 yards per reception, which gave the 5-foot-9, 200-pound Wilson all the reason to have plenty of confidence heading into his second season.

"I'm more comfortable out there," Wilson said. "I'm still young, I've got a lot to learn and I'm just trying to take advantage of this opportunity."

While it's early in June and there's plenty that hasn't been decided, Wilson has done enough to earn plenty of first-team reps with the Chiefs' offense through the first four days of OTAs.

But even with that trust and confidence, Wilson's approach hasn't changed.

"I still feel like I have to fight until it's guaranteed," he noted. "I'm fighting like I'm still the underdog."

Because he was a rookie last year, this offseason was the first opportunity Wilson had to work with his quarterback to try and develop an understanding of what he and Smith see against particular looks and coverages that the defense is showing.

"I feel like this offseason, early, we got a lot of work in—me and him," Wilson said of Smith. "When Jeremy (Maclin) came in, I feel like we got a lot of work—not even on the field, but off the field.

"In the film room, where we can see what each other is thinking at the certain time of a route, so that puts both of us in comfortable position."

Smith said after practice that both of the second-year receivers, Albert Wilson and De'Anthony Thomas, look much more comfortable now in their second seasons.

"They've kind of caught their breath and got their feet underneath them," Smith said. "Especially Albert Wilson, to see him come in and how hungry and ready he is for this next season. He sees his opportunity and knowing what he can do, you got a taste of it last year.

"He's extremely motivated to go out there and help us."

Wilson said he's already learned plenty from Maclin.

"He's an excellent guy," he noted. "He knows what he's doing. He's the coach on the field for me. He's just like Jason (Avant). They come in, I can look to them at any time—even right before a play, if I have a question from on the sideline.

"They're a great help out there for me."

As Wilson continues to prove himself throughout the rest of OTAs and into training camp, the game has slowed down for him now in his second season, which he believes will only help moving forward.
* *"It's slowing down a lot, but I feel like I still have a lot to learn," he said. "When you're out there and thinking about what you're doing, you won't be able to play fast.

"With me being a fast player, I have to know what I'm doing to be able to use my speed."
