GREEN BAY, Wis. -- The Green Bay Packers added a 12th wide receiver to their 90-man roster on Tuesday, signing one of the fastest players in pre-draft history in Terrell Sinkfield. Sinkfieldcaused a stir with his blazing 40-yard dash speed back in March at the University of Minnesota pro day. He clocked in at 4.19 seconds in his second attempt in the 40-yard dash. That's faster than the NFL Combine record of 4.24 seconds, set by Tennessee Titans running back Chris Johnson in 2008. Some questioned the legitimacy of the hand-timed reading, including ProFootballTalk.com, which said Sinkfield's time of 4.19 "doesn't pass the smell test." Then there was BusinessInsider.com, which broke down video of Sinkfield's run frame by frame and actually timed him at 4.16, a split-second faster than the original time of 4.19. Sinkfield's time of 4.19 came after his first run was clocked at 4.27 seconds. Scouts on hand couldn't quite believe what they saw on their stopwatches after his second run, so they had Sinkfield run one more time. Despite a slight stumble, he still crossed the line in 4.41 seconds for an average of 4.33. "The tape is out. I'm not disputing it or saying any specific time," Sinkfield told FOX Sports North on March 7. "I'm just back to training and hope to run fast again." Sinkfield practiced with Green Bay in the team's final open offseason training activity practice of the year, wearing No. 5. The Packers list Sinkfield at 6-foot and 200 pounds. He went undrafted out of Northern Iowa and originally signed with the Miami Dolphins before being released on May 28. As a senior at Northern Iowa, Sinkfield led the Panthers in receiving with 43 catches for 499 yards and four touchdowns. His junior season, the speedy Sinkfield had 28 catches for 464 yards and six touchdowns. Follow Paul Imig on Twitter
