Kyle Long will get a crash course on his job in the NFL with the Chicago Bears during the team’s rookie minicamp this weekend but then he’s on his own until the start of training camp. NFL rules prohibit the Bears’ first-round draft pick from participating in organized team activities that begin Monday and the mandatory veteran minicamp in June because of the class schedule at Oregon, where Long played this past fall. Specifically, NFL rules mandate that a draft pick cannot take part in anything other than the rookie minicamp until after the school he attends has completed final exams. Oregon uses a quarter system and final exams run through June 14. Like most teams, the Bears are holding their veteran minicamp from June 11-13. In total, the guard will miss 13 practices – 10 OTA sessions and three days of minicamp. An exception to the rule is there for players who have already graduated or were working on graduate level work during the previous year. Even if a player has left school, he’s not eligible to participate until after the school’s exams have been completed. It’s not a new rule and it is one that has kept Bears’ draft picks off the practice field during the spring in the past. The rule has not snagged a first-round draft pick for the club in recent memory.
