Beal will compete for a depth role when training camp begins, Corbin Smith of USA Today reports.
Beal started his last two college seasons at Oklahoma and posted 176 tackles, 2.5 sacks and one interception in 27 games. After being snubbed from the NFL Scouting Combine, Beal excelled at his pro day, posting a 4.58-second 40-yard dash and a 35-inch vertical. However, the 23-year-old went undrafted in part due to his small frame for a linebacker, checking in at just 223 pounds. The Seahawks are already strong at his position, but Beal's athleticism could allow him to compete for a spot on special teams.
