Northern Iowa WR reportedly runs 4.19 in the 40

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."
