INDIANAPOLIS -- Colts quarterback Anthony Richardson was placed on injured reserve Wednesday morning, meaning he'll miss at least the next four games with a right shoulder injury.
Richardson sustained an AC joint sprain in Sunday's win over the Titans. The team has been doing extensive consultation with doctors to determine the length of Richardson's absence and now believes he will miss between four and eight weeks depending on his rehab and whether surgery is required, a source told ESPN's Adam Schefter on Wednesday.
If Richardson misses only four games, he will be out for games at the Jaguars, home against the Browns and Saints, and a road game against the Panthers.
