Very cool gesture by the Chicago Bears ... the entire team wore No. 41 jerseys at practice to honor Brian Piccolo, who tragically died from cancer 52 years ago Thursday.
Piccolo -- who spent 4 seasons in the NFL (all with the Bears) -- was diagnosed with embryonal cell carcinoma, a form of testicular cancer, back in 1969 ... and sadly passed away at just 26 years old from the disease on June 16, 1970.
Bears head coach Matt Eberflus said he thought it was important for his team to be reminded of everything Piccolo did before his death, so he brought out the jerseys for Thursday's anniversary.
