When 49ers safety Eric Reid went down with 4:39 to go in the second quarter of Sunday's game against the Seahawks, it had the look of a devastating non-contact injury.

Head coach Kyle Shanahan called it a PCL injury on Monday that would not need surgery. On Tuesday morning, NFL Network Insider Ian Rapoport reported that Reid is only expected to miss a few weeks.

Reid's value to the 49ers was evident from the opening snap when he didn't fall for a Russell Wilson bootleg that sucked in the rest of the defense and downed the Seattle quarterback for just a 1-yard gain.

The former first-round pick and 2013 Pro Bowler fits perfectly into defensive coordinator Robert Saleh's scheme and was expected to be the centerpiece of the Niners' hard-hitting unit throughout the season. While that plan has skipped a beat, at least Reid will be available at some point again in the near future.
