ENGLEWOOD, Colo. — The Broncos wrapped up their pre-draft visits with the top four quarterback prospects when they welcomed Oklahoma quarterback Baker Mayfield to UCHealth Training Center on Tuesday.

Mayfield, the reigning Heisman Trophy winner, spent time with Broncos coaches and executives as part of Denver's pre-draft evaluation process.

"I went to Baker Mayfield's Pro Day and it was really good," Head Coach Vance Joseph said at March's NFL Head Coaches Breakfast. "He was accurate. He threw the ball well. He made every throw in the book. For a smaller quarterback, he can throw it long. He has a big arm. It's an accurate arm. He was very impressive."

The 23-year-old prospect threw for 4,627 yards, 43 touchdowns and completed 70.5 percent of his passes during his senior season with the Sooners. He tossed just six interceptions in 404 attempts.

Mayfield finished his collegiate career with the seventh-most career passing yards (14,607) among FBS quarterbacks.

President of Football Operations/General Manager John Elway previously dismissed concerns about the 6-foot-1 Mayfield's height.

"I think that [stigma] has been broken," Elway said at the 2018 NFL Combine. "You've got [Saints QB] Drew Brees—they've proven that you can do it. He's obviously very much a competitor. He's had a great college career and won the Heisman Trophy. He's proved he can play."

The Broncos previously hosted UCLA's Josh Rosen and Wyoming's Josh Allen, and a contingent of Broncos coaches and executives held a private workout in Los Angeles for USC's Sam Darnold.

Denver holds the fifth-overall pick in the 2018 NFL Draft, which begins April 26.
