The Seahawks added a pair of players to their roster Thursday, signing linebacker Dadi Nicolas and receiver Keenan Reynolds. Defensive ends Marcell Frazier and Noble Nwachukwu were waived to make room on the 90-man roster.

Reynolds, 23, was a 2016 sixth-round pick out of Navy, where he played quarterback for the Midshipmen. The 5-foot-10, 191-pound Reynolds finished his college career with an FBS record 88 career rushing touchdowns and 4,559 rushing yards, an FBS record for a quarterback. After making the move to receiver with the Ravens, Reynolds spent his rookie season on Baltimore's practice squad, then spent part of the 2017 season on Washington's practice squad.

Nicolas, 25, was also a 2016 sixth-rounder, going to Kansas City where as a rookie he appeared in 11 games, primarily on special teams. Nicolas, who is 6-3, 239 pounds, finished his rookie season on injured reserve with a patellar tendon injury that caused him to miss the 2017 season. He was released earlier this month by the Chiefs.

Frazier signed with the Seahawks earlier this month as an undrafted rookie out of Missouri, while Nwachukwu first joined the Seahawks as a member of the practice squad last season, then signed a futures contract in January.

The Seahawks also signed two more of their 2018 draft picks, linebacker Shaquem Griffin and cornerback Tre Flowers. With first-round pick Rashaad Penny signing Wednesday, the Seahawks now have eight of their nine picks under contract, with only defensive end Rasheem Green remaining unsigned.
