3:05pm: Brown has officially been moved to the Injured Reserve list. Head coach Andy Reid confirmed that Brown’s recovery timeline is now “months not weeks” (reported by ESPN’s Adam Schefter). This means Brown will be out of action for more than four weeks as the Kansas City team moves forward without him for the foreseeable future.
11:03am: Marquise Brown‘s SC joint injury will further delay his debut with the Chiefs. Veteran wide receiver Brown is being placed on injured reserve, according to insider Jordan Schultz. 
Testing has shown that Brown’s injury has not healed properly, leading to the decision for him to undergo a procedure on Monday for a proper recovery. Being placed on injured reserve means he will be out of action for at least four weeks after already missing the season opener for Kansas City.
Brown, 27, sustained the injury in mid-August, and his initial recovery timeline raised doubts about his availability for Week 1. Although there is no broken bone, Brown will still be sidelined for a significant period. This differs from Tyreek Hill’s similar injury in 2019, but Brown will miss playing time nonetheless.
While Brown had a 1,000-yard season during his final season with the Ravens, his time in Baltimore fell short of expectations. Following his time in Arizona, Kansas City signed him to a one-year contract worth $7MM with additional incentives. Brown’s ability to reach those incentives will be affected by his extended absence.
Kansas City prioritized adding depth at the receiver position in the offseason, including signing Brown and drafting Xavier Worthy on Day 1. Worthy had a strong NFL debut with two touchdown catches and is expected to continue contributing in the passing game. The Chiefs also have other receivers like Rashee Rice, Justin Watson, Skyy Moore, Mecole Hardman, and JuJu Smith-Schuster on the depth chart.
Brown will miss the next four games until the Chiefs’ bye week. He will be eligible to return after that, but bringing him back will count as one of the team’s eight allowed injured reserve activations.
