Ursua was sidelined at OTAs on Thursday after tweaking his knee, Curtis Crabtree of Sports Radio 950 KJR Seattle reports.
Coach Pete Carroll indicated the injury is not significant, so it looks like the team is just erring on the side of caution. Ursua has spent his first two seasons with Seattle, but primarily worked on the practice squad. He will look to earn a bigger role during training camp in 2021.
