Former Chicago Bears first-round draft pick Gabe Carimi was a no-show at Halas Hall on Monday when the team took the field for the first organized team activity of the offseason, according to a source familiar with the situation.

He was the only one eligible to attend who did not, according to a source. Rookie first-round pick Kyle Long is the only player who cannot participate in the remainder of the offseason program due to Oregon being on the quarter system and having final exams that run through June 14.

The only mandatory portion of the Bears' offseason program is the veteran minicamp in the middle of June, but the team typically has close to 100 percent participation in the organized team activities.

It was the first of 10 OTAs, and it's uncertain if Cariimi will attend Tuesday.

According to multiple sources, Carimi hasn't been with the team since he participated in the club's voluntary three-day minicamp held from April 16-18. Following the conclusion of the minicamp, Carimi informed the Bears he planned to skip the second phase of the Bears' offseason program that included individual on-field work and positional meetings in favor of returning to Arizona to continue his offseason training.

Carimi felt working out in Arizona gave him the best opportunity to return to the field healthy and avoid the knee problems that have plagued him the last two years, a source said.
