Steelers scout Mark Gorscak has been the starter for the 40-yard dash at the NFL Combine for 15 years. On Sunday, he will generate a little more attention when he wears a No. 50 #Shalieve shirt to honor injured linebacker Ryan Shazier. Gorscak will wear the shirt when the linebackers run in the afternoon. The NFL Network will promote the occasion and plans to air a response on social media from Shazier, Gorscak said. "I wanted to do something to bring attention to his cause," Gorscak said.
