Russell staggers off, Tuiasosopo warming up

MIAMI -- JaMarcus Russell is hurting. Marques Tuiasosopo is warming up on the sidelines.

The Oakland Raiders quarterback just staggered off the field after Miami Dolphins defenders Vonnie Holliday and Joey Porter crumpled him on a third-down scramble for no yards.

The play is being called a sack, with Holliday and Porter splitting it. Holliday got there first. Porter then smashed into Russell from behind.

Russell came off the field and headed straight for the bench. He was grabbing for his lower right leg. The Raiders' training staff is taping Russell's right ankle.

Andrew Walter, last week's starter for Oakland, was named the third quarterback before the game.
