According to Trevor Sikkema of The Draft Network, KJ Hamler out of Penn State tweaked his hamstring during training and will not be participating in the 40-yard dash at the NFL Combine. (Trevor Sikkema on Twitter)
Sikkema notes that Hamler reached 4.27 before getting hurt, which is absolutely flying. Hamler's going under the radar for fantasy football when he shouldn't be. Running a time like that on a national stage like the Combine would've brought him into the spotlight, but he remains one of the biggest steals in rookie ADP currently.
