FOREST LAKE, Illinois. The Chicago Bears will be without starting center Lucas Patrick indefinitely after the 28-year-old injured his right hand during practice Thursday.

“The reason I’m reporting this is because he will be out for a while, so it’s not just a soft tissue injury or something that could cause him to be out for a couple of days,” the coach said Friday. “Bears” Matt Eberflus. “No return schedule.”

Round six rookie Doug Kramer replaced Patrick on Thursday, and on Friday he split center representatives with reserve forward Sam Mastifer.

“Both of those guys did a good job of it,” said Eberfluss. “There is a lot of competition out there. Dieter [Eiselen has] played a bit in the center. I think it’s good for those guys.”

Patrick was one of Chicago’s top free agent newcomers after five seasons with Green Bay. He signed a two-year, $8 million contract with the Bears, looking to start at center, although he also has experience playing defense.

Chicago also didn’t have sophomore Theven Jenkins during Friday practice. Jenkins is “working on something with the coaches,” according to Eberflux, who called the former second-round pick “everyday.”

Jenkins underwent back surgery last August and as a rookie limited himself to 157 left tackle snaps. The Bears’ previous regime chose the former Oklahoma State player in the belief that he could turn into the franchise’s left tackle.

Jenkins hasn’t taken a rep in the first-team offensive line since the start of spring training. In May, he was replaced as a left tackle by rookie Braxton Jones and spent most of the OTA and mini-camp as a right tackle with the second squad.
