Saturday's slate of NFL preseason openers delivered the usual mix of quarterback battles and roster jockeying — and one gut-punch of an injury. Minnesota Vikings safety-turned-linebacker Jamal Adams was carted off the field in the second quarter of his team's game against the New York Giants at MetLife Stadium, just under three weeks after signing with the club.

Adams was in coverage tracking Giants receiver Calvin Austin when he stumbled and fell to the turf on what appeared to be a non-contact play, immediately grabbing his right knee. Vikings medical staff evaluated him in the blue medical tent before carting him to the locker room. He had played 11 snaps.

"THE INITIAL EXAM DOES NOT LOOK GOOD."

That was Vikings coach Kevin O'Connell's blunt assessment afterward, per Yahoo Sports, though he added the team would "wrap our arms around him top to bottom" while Adams awaits an MRI to determine the full extent of the damage. Adams, a nine-year veteran who signed with Minnesota on July 28 after a bounce-back 2025 season with the Las Vegas Raiders — his first full 17-game campaign since 2018 — had been expected to anchor the middle of Minnesota's defense this fall.

A former No. 6 overall pick by the Jets in 2017, Adams became one of the league's most decorated young safeties before a 2020 trade to Seattle kicked off a stretch marked as much by big hits as by injury absences. Healthy for the first time in years with the Raiders last season, he logged 45 tackles, five tackles for loss, a forced fumble and a sack across all 17 games. Minnesota brought him in on a one-year deal last month hoping that health would carry over; instead, three weeks later, he's facing new uncertainty.

A Rough Night Across the League

The injury added another chapter to MetLife Stadium's reputation as one of the league's more injury-prone playing surfaces, following high-profile non-contact injuries there in recent years to quarterback Aaron Rodgers, receiver Malik Nabers and pass rusher Nick Bosa. The Giants and Jets, who share the venue, have repeatedly faced questions about the turf, though no formal findings have tied Adams's injury specifically to the surface.

Elsewhere across a full Saturday slate, the Kansas City Chiefs rested Patrick Mahomes and gave extended reps to backup Justin Fields before rookie Garrett Nussmeier took over for his NFL debut against the Los Angeles Rams. In Cleveland, Deshaun Watson started the Browns' opener before giving way to second-year passer Shedeur Sanders for extended second-half work, part of the team's ongoing quarterback evaluation. The Carolina Panthers, meanwhile, suffered their own bad injury news: second-year edge rusher Nic Scourton went down with what the team confirmed is a season-ending knee injury, a significant early blow to a defense counting on him for a bigger role in 2026.

Preseason football carries a familiar tension for fans and front offices alike — meaningless in the standings, but often decisive for the players fighting for roster spots and, occasionally, costly for those already locked into the depth chart. Adams's injury is a reminder of the latter: a player who had just found a new team, and a new role, before his season may already be in jeopardy. The Vikings are expected to provide an update on Adams's MRI results in the coming days, which will determine whether his 2026 season is over before it begins.
