The speedy receiver from Missouri was slow to get up after chasing down a deep pass, did not return and the Bears had no real comment on the situation.

The Chicago Bears kicked off their rookie minicamp on Friday at Halas Hall, and the rookie jersey numbers were officially revealed. Second-round wide receiver Luther Burden III chose No. 87 -- but it wasn't his first choice.

Burden III wore the No. 3 at both Mizzou and in high school at Cardinal Ritter College Prep. The No. 3 he has worn throughout his career holds personal significance, as it’s a tribute to his namesake, per Sports Illustrated 's Joey Van Zummeran.
