Erickson remains in the NFL's concussion protocol as of Wednesday, Ben Baby of ESPN.com reports.
On the plus side, coach Zac Taylor relayed that Erickson is making progress, but the receiver's status for Sunday's game against the Ravens is unclear at this stage. With A.J. Green (ankle) still out and John Ross (shoulder) on injured reserve, Erickson -- if available -- would be in line for his share of snaps in Week 6 alongside starters Tyler Boyd and Auden Tate.
