ALAMEDA – The Raiders moved off-site, indoors and downgraded practices to walk-throughs twice last week due to poor air quality. Steady rain improved the air on Wednesday, but head coach Jon Gruden moved the practice inside just the same.
It's unclear exactly why the session was moved, especially with improved drainage at the team's practice fields and rain expected during Sunday's game at Baltimore.
They made the move anyway, and focused on mental prep for the upcoming Ravens game.
They put out an estimated participation reported after that off-site session, and receiver Jordy Nelson was considered limited. That's a step above last week, when he missed each practice with a bone bruise near his knee and then missed a victory over Arizona.
It doesn't guarantee he'll play the Ravens, but it's a sign his rehab is progressing. Raiders head coach Jon Gruden said Nelson's playing status remains unknown.
The Raiders need experienced receiver help. Brandon LaFell's on injured reserve now and Martavis Bryant remains out with a knee ailment, meaning Marcell Ateman, Dwayne Harris, Seth Roberts and recent active-roster additions Keon Hatcher and Johnny Holton are left in the pattern.
There isn't much established production from that crew, though tight end Jared Cook remains the top receiving option.
Leon Hall was out with a back issue suffered against Arizona, leaving Nick Nelson as the primary slot cornerback if he can't go versus Baltimore.
Defensive tackle Justin Ellis is expected to practice this week and receive a designation to return off injured reserve, but that didn't happen Wednesday. It could come before Thursday's practice.
