Alexander (head) was not listed on Wednesday's injury report.
Alexander exited Sunday's contest against the Giants and was evaluated for a concussion, but it appears he either avoided one or passed through the protocol with relative ease. Consider he's not listed on the injury report, there's little reason to suspect he will miss Sunday's matchup with the Falcons.
Alexander suffered a head injury during Sunday's win over the Giants and is being evaluated for a concussion, Kareem Copeland of The Washington Post reports.
Alexander played a rotational defensive role before exiting the Week 8 contest. If the rookie does enter the concussion protocol, he'll face an uphill battle to suit up for Washington's game against the Falcons in Week 9.
