Isaac Bruce, the NFL’s second all-time leading receiver, is now a“guest coach” for the Bears. Bruce, who gained most of his 15,208 receiving yards in the Rams’ famed “Greatest Show on Turf” offense, is helping Chicago’s young receivers adapt to new coordinator Mike Martz’s complicated offense.

“He’s teaching us the ins and outs,” second-year receiver Johnny Knox said after practice Thursday. “He’s been through a Martz offense. He knows how it works.”

Bears head coach Lovie Smith was an assistant with the Rams for three years during Bruce’s heyday.

“He’s a guy that believes in our system and knows how to be a great receiver in it,” Smith said. “Each year we can bring in a couple of guest coaches. We’re just going to let him teach the guys some of the tricks of the trade that he’s learned, nothing more than that.”

Bruce said the Bears have all the tools to run a Martz offense, starting with Jay Cutler as the trigger man.

“I don’t see much missing,” Bruce said. “They’ve got a quarterback who can wing it. I always like that. You’ve got guys on the outside who can make plays who are fast and who can run routes without breaking down. When you’ve got guys like that in this offense, it’s always good.”

Short visit to Soldier Field

The Bears return to Chicago today for their annual one day of training camp practice at Soldier Field.

“A lot of our fans have gotten a chance to come down here and watch practice, but each year we will come up one time and practice at Soldier Field to give some of thefans that don’t get an opportunity to see the Bears play during the regular season a chance to witness a (practice),” Smith said.

Injury report

Wide receiver Devin Hester and tight end Desmond Clark missed practice Thursday.

Smith said Clark took a scheduled day off while Hester was “a little bit sore, but he will be back out there tomorrow.”

Practice highlights

Greg Olsen reached back with one hand and made a left-handed grab of a tight end screen pass from Cutler. … Defensive end Mark Anderson came clean on a rush, but since quarterbacks aren’t allowed to be sacked in practice resorted to waving his arms in front of Cutler as if he were doing jumping jacks. … Greg Mathews came back to the ball and made a diving catch of a Caleb Hanie pass tipped by a defender. … Zackary Bowman almost had his fifth interception of training camp, but the practice refs ruled the ball hit the ground for a trap.
