Running back Montee Ball was clocked in the 40-yard dash at 4.46 seconds, a big improvement over his combine time, at Wisconsin's pro day.
The two-time All-American and NCAA's career touchdown leader ran a disappointing 4.66 last month at the NFL combine in Indianapolis.
Ball was among a group of former Badgers players who worked out for a large contingent of NFL scouts, coaches and general managers on Wednesday. At least 17 teams were represented at the event, including the Packers, Ravens, Seahawks, Saints and Patriots.
Ball's 40 time at the combine ranked 19th out of 33 running backs. He says he was dealing with a sinus infection in Indianapolis that might have slowed him down.
