1:50pm: Johnson will indeed need surgery, NFL insider Jordan Schultz reports. He adds a return could take place late in the campaign but there is a strong chance Johnson will be out for the remainder of the season. Fellow corner Terell Smith has already been lost to a torn patellar tendon suffered during the preseason. Chicago’s setup in the secondary will be worth monitoring given this latest blow dealt to the unit.
12:57am: Jaylon Johnson made his season debut yesterday but was unable to finish the game. The Bears’ top cornerback is now in position to miss an extended period. 
Johnson missed training camp as well as Chicago’s season opener while recovering from a groin injury. During the second quarter of the team’s blowout loss against the Lions, he reaggravated the ailment. As a result, ESPN’s Adam Schefter and Courtney Cronin report Johnson is out indefinitely.
The full extent of the injury is unknown at this point. Surgery could be on the table, depending on what further testing reveals. In any event, losing Johnson for an extended stretch will deal a notable blow to the Bears’ defense. The unit struggled mightily with and without him on Sunday, and being shorthanded in the secondary will be an unwelcomed development as the team looks to recover from its 0-2 start.
Johnson is in his sixth NFL season, each of which have come as a member of the Bears. The 26-year-old received the franchise tag last offseason to prevent a potential free agent departure. Johnson later signed a four-year, $76MM deal ensuring his status as a foundational member of the team’s secondary. He earned a second straight Pro Bowl nod last season but missed considerable time during the summer in advance of the current campaign.
Johnson was activated from the PUP list during roster cutdowns, allowing for him to return within the first four weeks of the season. The former second-rounder managed to do so, but after a brief spell on the field he will be sidelined for a notable stretch. Slot corner Kyler Gordon – who landed a lucrative new deal this spring – has yet to play this year, so Johnson’s absence could be particularly troublesome if Gordon remains unavailable for Week 3.
Chicago allowed a fourth-quarter comeback against the Vikings in Week 1 before surrendering 52 points against the Lions yesterday. Improvements on defense will be sought out over the coming weeks, and the team’s secondary will be a unit worth watching closely. Johnson will not be part of the Bears’ efforts to take a needed step forward for at least the time being, though.
