The Bears plan to sign quarterback Trace McSorley to their practice squad, his agent indicated on Twitter, which appears to be a precaution in case starter Justin Fields goes on injured reserve.
The team already expects Fields to be out Sunday against the Raiders, leaving undrafted rookie Tyson Bagent to start and Nathan Peterman as the backup. If the Bears add McSorley to the active roster by Saturday, they can designate him as their emergency third quarterback.
Fields is nearly certain to miss time after dislocating his thumb on his throwing hand and would be out a minimum of four games if the Bears put him on IR.
