ALAMEDA – Raiders left guard Kelechi Osemele missed Wednesday's practice with an ankle injury, the team reported.
Osemele suffered the injury during a victory over San Diego, but never missed a snap. The Pro Bowl player could be resting his ankle before playing on Saturday against Indianapolis, though that remains uncertain at this point. There is no initial alarm over Osemele being down.
Osemele is a tough customer and will play through pain to stay on the field and active in an important game.
Raiders rookie edge rusher Shilique Calhoun has missed four straight games after undergoing a procedure on his knee. He got hurt against the Houston Texans and has been stuck on the sideline ever since, leaving the Raiders thin at his position.
Bruce Irvin has played virtually every snap since, only with brief respites from James Cowser. Calhoun could be back in the fray this week or next, because progress is being made.
Calhoun was a limited participant in Wednesday's practice, a day after doing side work.
A pair of defensive starters also remain out. Safety Karl Joseph hasn't practiced since injuring his toe against Buffalo, though he did some side work with a trainer during Wednesday's morning walk through.
Stacy McGee is also down with an ankle injury.
The Raiders are relatively healthy outside the aforementioned trio with several limited participants expected to play on Saturday against Indianapolis.
As a matter of procedure, this was the team's first participation report of the week. They will offer info for Wednesday and Thursday, and then estimate participation levels on Friday despite that being a dark day heading into a Saturday game. The Raiders will offer a final injury report that day.
