WR Paul Richardson announced via Twitter that he had signed his contract with the team Tuesday afternoon. A team spokesman confirmed the signing.
Richardson was Seattle's top selection in the draft, selected with the No. 45 overall pick in the second round.
As a senior at Colorado, Richardson caught 83 passes for 1,343 yards and 10 touchdowns in 12 games for the Buffaloes.
Richardson practiced just one day with the team during last weekend's rookie mini-camp. He flashed his speed and catching ability all over the field, including a 63-yard touchdown catch from QB Keith Price.
However, Richardson banged his shoulder diving for a pass on the final play of Friday's practice and sat out the final two days as a precaution. Head coach Pete Carroll said Richardson would be fine a couple of days.
Seattle has now signed five of their nine draft picks. Richardson, DE Cassius Marsh, DT Jimmy Staten, CB Eric Pinkins and FB Kiero Small have all signed their rookie deals.
T Justin Britt, WR Kevin Norwood, LB Kevin Pierre-Louis and T Garrett Scott remain unsigned.
