Based on the wiki, the situation is a potential hamstring concern, not a confirmed serious injury. Skattebo surfaced what looked like a hamstring issue late in the game on his 42-yard overtime run, but there's no word yet on severity or tests.
The key cushion here: the Giants have their Week 8 bye right after this game, which gives him a full week to recover without missing time. (from the Cam Skattebo page)
Sal Vetri flagged on his channel that Skattebo is only at 55% of snaps with Devin Singletary (29%) and Tyrone Tracy (15%) also involved — so even if the hamstring lingers, the Giants have a committee they can lean on. The bye week makes me optimistic this doesn't cost him games, but it's worth monitoring for practice reports before Week 9.
