ALAMEDA -- Quarterback Matt Schaub missed his second day of practice Monday, watching in a ball cap as the Raiders finished warm-ups and drills during the portion open to the media.
Coach Dennis Allen said Sunday Schaub had some elbow soreness.
Allen and Schaub are both scheduled to speak with the media following practice.
Players who were not practicing included linebacker Sio Moore (neck), linebacker Nick Roach (concussion), tackle Menelik Watson (hip flexor), cornerback Chimdi Chekwa (knee), tight end David Ausberry (knee) and cornerback Taiwan Jones (not disclosed).
Ausberry was working on a separate field along with cornerback DJ Hayden and Jones.
The Raiders must trip eight players from the roster by Tuesday at 1 p.m. Hayden and guard Lucas Nix are eligible to be placed on the physically unable to perform list at that time and then wouldn't count toward the roster.
Two more players -- running back Kory Sheets (Achilles) and tight end Nick Kasa (torn ACL) are eligible to be placed on injured reserve and also wouldn't count.
