RENTON, Wash. -- The Seattle Seahawks put on helmets and shoulder pads Tuesday during their third training camp practice. Here's what stood out.

Luke Joeckel and Frank Clark got into a minor scuffle.

Last summer, Seahawks training camp featured what seemed like at least one fight a day. This year has been quieter, but things started to get chippy today. On one play, it looked like Joeckel got knocked to the ground, and he grabbed a hold of Clark's leg, which Clark didn't appreciate.

Soon, Germain Ifedi and Cliff Avril got involved as the two sides went at it before being separated. One player who didn't take the skirmish too seriously was Bobby Wagner. The Seahawks' middle linebacker bounced up and down to the music by himself, presumably enjoying the heated moment while his teammates calmed down.

Earlier, Thomas Rawls mixed it up with K.J. Wright during a run drill before teammates separated them. Rawls continues to be a ball of energy. One of the loudest sounds of camp so far was him colliding with linebacker Michael Wilhoite during a blitz pickup drill.

The offensive linemen held their own during one-on-ones.

This was the first day of one-on-one drills between offensive and defensive linemen, and Tom Cable's group held its own.

Germain Ifedi did a good job against Cliff Avril. Mark Glowinski handled Nazair Jones. And Oday Aboushi got the best of Michael Bennett.

It was only one session, and the defensive line is the more talented and accomplished unit. But it had to at least be an encouraging sign for Cable that his group competed.

Chris Carson could be a name to watch in the preseason.

From a physical perspective, Carson stands out. The seventh-round pick out of Oklahoma is 6-foot, 218 pounds and rocked up.

Today's practice ended with Carson bursting up the middle and racing to the end zone for a touchdown -- much to the delight of Russell Wilson and Doug Baldwin who jogged downfield to congratulate him.

Carson was a favorite of Pete Carroll's during the draft. He'll likely have to beat out Alex Collins to make the 53-man roster. But when the preseason begins, Carson is somebody to keep an eye on.

Jeremy Lane continues to impress.

The veteran cornerback has been arguably the team's most impressive player through the first three practices. During one-on-ones today, Lane stuck with Paul Richardson and broke up a pass.

Going into camp, I thought someone like rookie Shaquill Griffin would have a great chance to compete for the starting corner job opposite Richard Sherman. But Lane is competing like he's not giving up the spot. Carroll said it was clear that something clicked with Lane this offseason. It's still early, but Lane is clearly the favorite to start.

Extra points.

Kicker Blair Walsh has not missed a field goal in the past two days after looking shaky on Sunday. ... Overall, the corners had a strong day. In addition to Lane, Neiko Thorpe broke up a pass intended for Richardson. And Sherman looked good during one-on-ones against wide receivers. ... Jimmy Graham made the catch of the day. He found a spot in between defenders, but Wilson's throw was a little off-target. Graham reached out with his left hand, batted the ball to himself, juggled it a couple times and then came down with the grab.
