Colby Parkinson (Rams) Listed Day-to-Day with Right Shoulder AC Joint Sprain

Rams tight end Colby Parkinson sustained an AC joint sprain to his right shoulder during the Broncos game, and is currently listed as day-to-day. The injury is confirmed by team report; the grade is inferred as Grade 1 based on the day-to-day designation — no imaging confirmation has been publicly disclosed.

The acromioclavicular joint is the bony junction at the top of the shoulder where the clavicle meets the acromion. A Grade 1 sprain means the ligaments are stressed but structurally intact — the joint holds, and most athletes recover within one to three weeks with conservative management. For a tight end, the right shoulder carries meaningful functional weight in both blocking and pass-catching, so even a minor sprain warrants monitoring.

Parkinson's injury occurred on September 27, putting him two days into what is typically a one-to-three-week recovery window. At this stage, a day-to-day designation is consistent with the biology — Grade 1 AC sprains often allow return within the week depending on pain tolerance and functional testing. The key watch signal here is how he moves through practice participation mid-week: a player who progresses to full participation by Friday is a strong plays candidate; stagnation or deterioration would warrant a more conservative read.
