Northern Iowa receiver Terrell Sinkfield just wanted to run fast when he showed up at the University of Minnesota Pro Day on Monday.

Sinkfield, a former sprinter from the Minneapolis area, ran so fast that he now has turned the heads of NFL scouts and general managers, clocking in at 4.19 in the 40-yard dash in one of his runs. That unofficial time is five-hundredths of a second faster than Chris Johnson's official record at the NFL Combine of 4.24 set in 2008.

Sinkfield was also timed at 4.27 and still had a 4.41-second time in a run where he stumbled, according to FoxSportsNorth.

Asked how he ran so fast, Sinkfield said, "Just some determination. That was the expectation, really. Aim big. I was trying to get that 4.1."
