The Seahawks signed five players who participated in last weekend's rookie minicamp, cornerback Jamal Marshall, linebacker Pete Robertson, fullback Taniela Tupou, tight end Ronnie Shields and receiver Tyler Slavin.
To make room on the 90-man roster, Seattle released defensive tackle A.J. Francis, defensive tackle Lars Koht and safety Robert Smith, and waived/injured cornerback Mohammed Seisay and receiver Jeff Fuller.
Shields and Slavin were both signed to future contracts earlier in the offseason, then released prior to last week's minicamp. Tupou, who is from Marysville and played at the University of Washington, spent time at both defensive tackle, his college position, and fullback during minicamp. Last season the Seahawks occasionally used fullback Will Tukuafu at defensive tackle, and one of this year's undrafted free agent signings, Florida International's Brandin Bryant, is listed as both a fullback and defensive tackle, having played defense in college.
Marshall, a 6-foot-2, 210-pound rookie out of North Texas, stood during his tryout over the weekend, including an interception to end Sunday's practice. Robertson, who is 6-2, 233 pounds, played defensive end at Texas Tech and had 17 sacks over the past two seasons.
The final day of Rookie Minicamp took place in the indoor practice facility where the team practiced on similar turf they could be playing on come August.
