Lamont Roach is totally unbothered by rival Gervonta Davis ... the boxing star tells us he's completely focused on putting Isaac "Pitbull" Cruz's lights out, and doing it quickly!
"Nobody wants to be in there for a long time, so hopefully I catch him with one that's gonna make him go to sleep. If not, I'll just beat him up for 12 rounds straight," 30-year-old Roach (25-1-2), told TMZ Sports ahead of Saturday's highly anticipated bout.
27-year-old Cruz (28-3-1) is no walk in the park, and Roach knows it.
