Seahawks sign offensive tackles Raiqwon O’Neal and McClendon Curtis, place Abraham Lucas on IR

The Seahawks added offensive line depth to their roster on Wednesday, signing a pair of undrafted rookies to their 53-man roster.

Tackle Raiqwon O’Neal was signed from the Tampa Bay practice squad, while McClendon Curtis was signed from the Las Vegas practice squad.

Abraham Lucas, who left Seattle’s Week 1 game with a knee injury, was placed on injured reserve, meaning he will miss at least four games before being eligible to return.

O’Neal, who went undrafted out of UCLA, started all 13 games at left tackle last season. Before transferring to UCLA, Smith played at Rutgers, where he started 21 games at left tackle over three seasons.

Curtis, who signed with the Raiders as an undrafted free agent out of Tennessee-Chattanooga, started 38 games in his college career, primarily playing right guard but also left tackle and left guard.

With Lucas now going on IR and Charles Cross dealing with a toe injury that kept him out of Sunday’s game, the Seahawks have been busy adding tackle help this week, signing veteran Jason Peters and Greg Eiland to their practice squad on Tuesday before adding Curtis and O’Neal Wednesday.
