Coach Pat Shurmur said McCoy is improving and remains day to day. McCoy did not travel with the team for Sunday's game in Arizona. His backup, Seneca Wallace, started Cleveland's 20-17 overtime loss to the Cardinals.
Shurmur would not discuss which of his QBs would start this Saturday at Baltimore. Shurmur will wait until McCoy is cleared before announcing his starter.
Shurmur does not know if McCoy will practice this week.
A league source had told ESPN NFL Insider Adam Schefter on Sunday that McCoy was expected to take and pass his concussion test early this week.
