According to ESPN's Adam Schefter, McConkey received the questionable designation on the Chargers' latest injury report. The second-year receiver did not participate in Thursday or Friday's practices as he continued dealing with the issue.
McConkey's back problems first became noticeable before Los Angeles' Week 9 game. He was active for the matchup against the Houston Texans but did not take the field because of back spasms. His limited involvement during the team's preparations for Baltimore adds another concern ahead of Monday's kickoff.
The Chargers will likely make a final decision closer to game time. McConkey's status could remain uncertain until the team releases its inactive list, which typically comes around 90 minutes before kickoff. If he cannot play, or is available only in an emergency role, Quentin Johnston, Tre Harris and KeAndre Lambert-Smith could handle larger responsibilities in the passing game.
There is some positive news for Los Angeles, as Harris has been cleared from the injury report and is no longer carrying a game designation. His availability would give quarterback Justin Herbert another option if McConkey misses the contest.
Ladd McConkey has recorded 17 receptions for 286 yards and one touchdown across six games this season. His absence would be a notable setback for the Chargers as they prepare for a difficult road test against Baltimore.
