"Titanium plates were installed," Lamas wrote. "I asked the doctor to install laser guns in my mouth that I could activate with my tongue and shoot through my teeth but he said that was impossible."
He added: "For my beloved city of Chicago, I’m sorry I let you down again, but I wanted to thank you all for the cheers you gave me during my introduction, it gave me chills and I will never forget it, Chicago truly has the best fans. For now, it’s quality time with my family and baby No. 3 coming early August, which puts in perspective what’s really important in life."
