Spruce sprained a knee and is expected to miss a week or two, Rich Hammond of the Orange County Register reports.

Undrafted despite his solid college track record, Spruce made his argument for a roster spot during the Rams' exhibition opener, catching six passes for 51 yards and a touchdown. The injury could lessen his odds of sticking on the final roster, but he does still have shot to make it back for the final preseason game or two.
