49ers WR Jordan Watkins is expected to miss about a month with a high ankle sprain.
The hits keep on coming for the Niners, who are expected to be without Brandon Aiyuk (knee) for at least the first month of the season, and are at risk of being without Jauan Jennings (calf) as well. Jacob Cowing is also battling a hamstring injury, although Kyle Shanahan said he could return to practice on Tuesday. Still, it goes without saying that the Niners’ receiver room is banged up, and Watkins had a chance to see some work early in the season with the injuries piling up. It was reported earlier this month that Watkins was ‘in the mix’ for WR3/WR4 duties. A month-long absence means Watkins could be at risk of missing the first month of the season, but we’ll likely get more clarity on that as Week 1 draws closer.
