With 10 training camp practices in the books and the preseason opener only days away, several Seahawks have bolstered their stock battling for starting jobs and roster spots, while others have plenty of work left to do.

As expected, the Seahawks will open training camp without fifth-round pick Rylie Mills able to practice, but several other undrafted rookies also will be sidelined indefinitely.

Jalen Sundell wasn’t even on the roster until late July and Cody White looked to be on the outside looking in at receiver for the Seahawks, but both wound up surprising in training camp and seeing action in regular season games. Which dark horses could emerge this year?

Possessing a nose for the football and outstanding coverage skills, D’Eryk Jackson hopes to put his previous injury woes behind him and prove he still has the goods to be an NFL linebacker with the Seahawks.

Shaking up the back end of their roster, the Seahawks awarded two tryout players who excelled at rookie minicamp by signing them to contracts on the active roster heading towards OTAs.

Earning a roster spot the unconventional way, the Seahawks will add D’Eryk Jackson to the mix to compete for a reserve role at linebacker this summer after standing out as a tryout player at rookie minicamp.
