Suggs' absence was expected because the three-time Pro Bowl player has not signed his franchise tender, which was offered by the Ravens in February.
By rule, a player cannot participate in NFL camps until the tender is signed. Suggs and Ravens general manager Ozzie Newsome are still negotiating in hopes of reaching a long-term deal.
"[His contract situation] is being worked out between his agent and Ozzie," Ravens coach John Harbaugh said of Suggs' absence. "But football-wise we're in contact with him. He wants to come back, you can bet on that. He would like to be here in practice."
Suggs, 26, recorded 68 tackles, eight sacks and two interceptions for Baltimore in 2008. The former first-round draft pick was an important cog in the league's No. 2-rated defense, which helped the Ravens advance to the AFC Championship Game.
