Video: This Is What Really Happened In Week 2
I loved Caleb Williams in fantasy, who by the way looks like he just has a grade one hamstring. So maybe we'll be able to play as soon as week four. I don't think he will play in week three.

Grade one hamstring; unlikely Week 3, possible Week 4 return

Williams has a grade one hamstring and may be able to play as soon as Week 4, but is unlikely to play in Week 3. The timeline suggests a relatively minor injury with potential for near-term return.
