Coach John Harbaugh noted Monday that Ali is in concussion protocol, Jonas Shaffer of TheBaltimoreBanner.com reports.
Per Harbaugh, the status of Ali -- who suffered a reported stinger in the Ravens' preseason opener -- is iffy for the team's regular-season opener, Thursday, Sept. 5 against the Chiefs. With fellow RB Owen Wright having suffered a broken foot Saturday, the Ravens' backfield depth behind Derrick Henry and Justice Hill is currently taxed. As a result, it wouldn't be surprising to see Baltimore address the situation before, during or after initial roster cut downs.
