Bentley (pectoral) will be placed on injured reserve Wednesday, Mike Reiss of ESPN.com reports.
Bentley's injury details have been a bit of a mystery, with reports more than a week ago stating he'd likely be out for the remainder of the season with a torn pectoral muscle, after initial reports suggested he may miss no time at all. A move to IR would at least confirm he'll miss the team's next four games but still won't confirm whether he'll be out for the season.
