http://espn.go.com/blog/chicago/bears/ June, 17, 2014 5:56 PM ET By Jeff Dickerson | ESPNChicago.com LAKE FOREST, Ill. -- Jordan Palmer's return from a minor strain to his right throwing shoulder did little to clear up the Bears' fuzzy picture at the backup quarterback position. Limited by the injury the last two weeks of organized team activities (OTAs), Palmer had full participation in the Bears' first of three mandatory minicamp workouts held on Tuesday, but he seemed to struggle with his accuracy at times, although Palmer reported no issues with his shoulder when he spoke with reporters after the practice. "I felt great," Palmer said. "It was good to be back in the mix. I thought we had a pretty good practice today. [There wasn't] too much [rust]. It's still football. We're still wearing shorts and T-shirts, but it was good to be back out there with the guys." Meantime, newcomer Jimmy Clausenmade the most of his limited reps, and even spent the end of practice occasionally working in with Palmer and starter Jay Cutler, while developmental quarterbacks David Fales and Jerrod Johnson took turns running the scout team offense on the other side of the field. Clausen signed a one-year deal with the Bears on June 7. "I watched Jimmy when he was at Notre Dame," Cutler said. "Liked him. He was in a tough situation out there in Carolina. Offensive line was pretty rough; he was getting hit a lot. The system turned over on him. He throws the ball well. I didn't have any input on bringing him here, though. Once he did get here, though, he was in the quarterback room over the weekend three straight days grinding way, trying to figure out this offense. He was peppering me and David Fales, [quarterbacks coach] Matt Cavanaugh, all questions. So he's been working hard. I think he likes the opportunity he has here. He's a little bit humbled going through the experience of being on the streets and getting picked up again. He's got a good attitude. Training camp and preseason, we'll see how it works out." Clausen's first task is sticking on the roster long enough to report to training camp with the club on July 24. But the odds of that happening seem promising. However, with five quarterbacks currently under contract, the Bears are likely to jettison at least one reserve quarterback in the coming weeks. "I don't know if that's ever happened [going to camp with five quarterbacks], not in the times I've coached the position," Bears head coach Marc Trestman said. "These next two days are certainly critical; we've got to continue to analyze the situation. It would be hard to, we need legs at camp, but we'll see. We'll make that decision, and we don't even have to make that decision this week, we'll make it before the start of training camp. I think we've got five viable guys. You take Jay out of it and we've got four guys that are really competing hard and all have the requisite skill set to play in the National Football League, we've just got to continue to watch it and see how it unfolds." Here are other observations from the Bears' opening minicamp practice: • The Bears rested starting right tackle Jordan Mills (foot) after the second-year offensive lineman returned from offseason surgery in May to participate in OTAs. Mills called his absence "precautionary," but wasn't sure if he'd practice on Wednesday or Thursday before the team breaks for the summer. "It's just a little precaution, nothing major," Mills said. "I'm 100 percent. I was kind of mad I couldn't go out there and practice today with them but the trainers know best. They just wanted to rest my foot a little bit. • Safety Chris Conte, linebacker Khaseem Greene and defensive tackle Will Sutton were all excused for "family reasons" according to Trestman. Matt Slauson (shoulder) was present but continued to sit out. Safety Craig Steltz took part in certain individual drills as he recovers from an offseason leg issue. • Veteran Kelvin Hayden was the Bears' fourth cornerback when the team went to its dime package on defense. • Trestman called D.J. Williams "the lead dog" at middle linebacker, but 2013 second-round pick Jon Bostic took reps with the first team at linebacker in the nickel package, and could definitely still challenge for the open outside linebacker spot if Williams manages to stay healthy and solidifies the middle in the club's base defense. • Safety Ryan Mundy dropped an easy pick when a Cutler pass sailed off its mark close to the right hash. • Linebackers Jerry Franklin and Christian Jones saw action with the No. 2 group. Jones, an undrafted rookie free agent out of Florida State, has opened some eyes in the offseason program. • With Mills out, Michael Ola spent time at right tackle with the starters. Brian de la Puente continued to take reps at left guard. • Converted running back Jordan Lynch ran a wheel route out of the backfield and caught a diving touchdown pass from Johnson late in the session. • Rookie cornerback Kyle Fuller broke up a pair of passes in team drills. • Brandon Marshall burned Tim Jennings for a long touchdown reception. On the play, the Bears had speedster Chris Williams lined up in the slot. • The Bears invited numerous NFL player agents to Halas Hall on Tuesday to watch practice inside the Walter Payton Center. Agents are frequently spotted catching up with their clients at training camp, but rarely are large groups of agents permitted to observe a workout held at the team's facility.
