One rookie defensive tackle was on his way in, as the Jaguars awaited word on another rookie tackle the team hopes hasn't been lost to an injury.

First-round draft pick Tyson Alualu arrived at EverBank Field on Tuesday and signed his contract as his teammates were going through a morning practice under a scorching sun. Meanwhile, third-round pick D'Anthony Smith was undergoing an MRI on the injury he sustained to his right foot early in Monday evening's practice.

"We're pleased to have him in. We think he's a good player. We'll ease him in, get him some action," coach Jack Del Rio said of Alualu. "He missed a little bit but with the commitment he made in the offseason, he'll be able to make an impact."

"I'm excited it's behind me," Alualu said of the contract negotiations, which caused him to miss the first four-and-a-half days of training camp.

Del Rio said the much-publicized Oklahoma matchup between Alualu and Vince Manuwai, both of whom grew up in the same Honolulu neighborhood, will be conducted in Wednesday afternoon's practice. Alualu is expected to join his teammates for Tuesday evening's full-pads practice.

Alualu told reporters, "I have to use my wisdom to spend (the money) wisely. I'm going to use it to help my family and my community."

His father is the pastor of "Solid Rock Fellowship Assembly of God" in Honolulu and Alualu said he will use the money from his signing bonus to help build a new church on a vacant piece of ground near his neighborhood.

The Jaguars, of course, hope to build the defense of their future around Alualu, the 10th pick of the draft, who will undoubtedly step into the starting lineup.

"I have a lot to do to meet the expectations," Alualu said.

Smith, the team's second pick in this past April's draft, was carted from the field on Monday. Del Rio said, "As I get details, I'll provide them to you. It's the foot, ankle area. It could be a problem. I'll let you know."

Meanwhile, Del Rio gave thumbs up to second-year defensive tackle Terrance Knighton's quest to shed weight.

"Terrance is doing a nice job of getting down. He's in the low forties. He's a big guy. We want him big. I don't want him to be skinny. It's amazing his footwork is as good as it is," Del Rio said.
