OTAs are voluntary, but at the moment, there is no anticipation as to when Carimi, the Bears' first-round pick in 2011, will be joining his Bears teammates. Carimi wasn't present Tuesday at practice, which was open to the media, after sitting out the first day on Monday.
"Obviously, we talk and he's doing what's best for him," center Roberto Garza said. "That's all I have to say about that."
Carimi started the first 10 games of last season at right tackle before losing his spot to veteran Jonathan Scott. He later started three games at right guard after injuries decimated the Bears' offensive line.
New Bears coach Marc Trestman said during voluntary minicamp in April that he sees Carimi as "more guard" moving forward. It's been expected that Carimi would compete against 2013 first-round pick Kyle Long, Matt Slauson and James Brown at the position.
Carimi was never healthy last season after dislocating his right knee cap in Week 2 of the 2011 season and later requiring multiple surgeries.
Carimi, who did participate in voluntary minicamp, said his goal for the offseason was "just getting healthy. Just feeling better and feeling back to my old self like my rookie year."
Garza said there "a lot of changes" from last season to adjust to and that's why OTAs are important.
"From the weight room to the way the practices are being run to the meetings, we have a whole new staff, a whole new offense to learn," Garza said.
Garza centered a completely new offensive line on Tuesday with tackle Jermon Bushrod and Slauson to his left and tackle' J'Marcus Webb and Brown to his right.
"We just have to work together, and obviously, these OTAs are great for that, learning how each other plays, trusting each other," Garza said. "There's a big process that has to go into us working together and it starts here."
