Bears elevate Mills, Long; Webb to 2nd team BOURBONNAIS, Ill. -- The Chicago Bears returned to the practice field following their preseason opener in Carolina with a different starting combination on the right side of the offensive line with rookies right tackle Jordan Mills and right guard Kyle Long replacing James Brown and the embattled J'Marcus Webb. [+] Enlarge Jerry Lai/USA TODAY SportsBears guard Kyle Long is working out with the first team at camp. The Bears inserting 2013 first-round pick Long into the starting lineup is hardly a surprise since both he and Brown had been alternating reps with the No. 1 offense since the beginning of training camp, but Sunday marked the first time Mills, the Bears’ 2013 fifth-round choice out of Louisiana Tech, had jumped in front of Webb on the depth chart. Webb spent the practice at left tackle with the second team while Eben Britton worked at right tackle with the No. 2s. Veteran Jonathan Scott remained sidelined with a knee injury. “It’s a great opportunity, it’s humbling, having Roberto Garza, Webb, Jermon Bushrod, Matt Slauson, the whole offensive line helps me,” Mills said. “They’re in your ear every time I make mistakes I can go to the sideline expecting some criticism, constructive criticism -- what to do here, you need to step this way, be a little bit lower, so it’s been great working with them. In my eyes, these dudes are all Hall of Famers in my eyes, so just to be here is so humbling.” Bears head coach Marc Trestman cautioned that nothing is set in stone on the right side, but said Mills and Long will continue to get the bulk of the practice reps in the next couple of days leading up to the second preseason game against the San Diego Chargers, where the duo is likely to open up the game as starters. However, Trestman stopped short of saying the team was sending a message to Webb. “I think we've been very clear with J'Marcus about what we're doing,” Trestman said. “I said it last week that there's been an up-and-down performance level by J'Marcus but we were still going to do this. We were still going to give work to the other guys and see what they could do as well. So we'll evaluate it. We're going to go through the week like this. We'll evaluate the game and move forward into Oakland."
