Top running back prospect Christian McCaffrey has declined all private workout requests by NFL teams ahead of the 2017 draft, Mike Florio of Pro Football Talk reports.

The former Stanford standout’s stance apparently hasn’t affected his draft stock, however. He’s still expected to be taken around the middle of the first round come the end of April, and could be off the board before the 15th overall pick (held by the Indianapolis Colts), according to Florio.

McCaffrey worked out at both the NFL Scouting Combine and his pro day. He impressed scouts at both events by excelling in the 40-yard dash, vertical jump, three-cone drill, and 20-yard shuttle, as well as showing off his skills as a route runner.

The 20-year-old was considered a borderline first-rounder entering the offseason, but his strong combine and the big-play ability and versatility he showed on tape have launched him up draft boards to the point that he apparently doesn’t want to risk injury by working out for teams.

Top cornerback prospect Sidney Jones highlighted the dangers of pushing to improve draft stock when he tore his Achilles at his pro day. Once a lock to be selected in the first round, Jones will likely have to wait until Day 2 to hear his name called.

McCaffrey is theScore’s No. 1-ranked running back, ahead of more traditional runners Leonard Fournette and Dalvin Cook.
