LAKE FOREST, Ill. (CBS) — Bears receiver Alshon Jeffery is injured again, having tweaked his groin Wednesday. He didn’t participate in Thursday’s practice.

Jeffery has played in just four of the Bears’ eight games but is still the team’s second-leading receiver with 33 catches for 492 yards and two touchdowns.

“If he can’t go, we’ve had life without him,” Bears quarterback Jay Cutler said. “We’ll figure it out.”

Unfortunately for Cutler, the Bears were also without receiver Eddie Royal in practice, who was sidelined again with a knee injury. Royal has missed two games this season with a knee injury. Bears running back Matt Forte (knee) participated in a limited role for the second straight day.

In speaking to the media, Bears head coach John Fox was asked if Jeffery is prone to injuries.

“We’re in a very physical, combative game,” Fox said. “I’ve heard medical people say, ‘Well, (Jeffery) needs some rest.’ Well no kidding.”

Additionally, linebacker Pernell McPhee (knee) and defensive tackle Mitch Unrein (illness) didn’t practice, while linebacker Shea McClellin (knee), cornerback Tracy Porter (hip), safety Antrel Rolle (ankle) and offensive tackle Jermon Bushrod (shoulder) were limited.

The Bears (3-5) are Rams (4-4) kick off at noon on Sunday in St. Louis.
