ALAMEDA, Calif. (AP) - First-round draft pick Darrius Heyward-Bey sat out the final day of the Oakland Raiders' minicamp Sunday because of a sore hamstring and fatigue.
Second-round pick Mike Mitchell and fourth-rounder Louis Murphy also missed the workout for similar reasons.
"Just tightened up," Heyward-Bey said. "My legs are a little too tight. Running too fast."
Heyward-Bey, who had the fastest 40 time at the Scouting Combine in February, was injured late in Saturday's practice and did not work out in the afternoon. He spent Sunday as a spectator alongside Murphy and fellow wide receiver Javon Walker, who is recovering from offseason knee surgery.
"It's the toughest transition for the rookies with all the running we do," head coach Tom Cable said. "You just want to be smart with them. It's precautionary."
Along with the three receivers and Mitchell, the Raiders were also without left guard Robert Gallery (calf), defensive tackle Gerard Warren (pectoral muscle), defensive end Derrick Burgess (stomach flu) and reserve offensive lineman Paul McQuistan, who is still recovering from knee surgery last season.
The Raiders will resume their offseason workout program on May 19.
