Fooch's update: The 49ers confirmed the addition.
The San Francisco 49ers released Chris Cook Wednesday morning, and Wednesday afternoon they made a corresponding roster move. Mike Garafolo is reporting the team is signing wide receiver Nigel King, according to his agent. King was an undrafted free agent following the 2015 NFL Draft, after foregoing his senior season at Kansas. He spent some time with the Miami Dolphins earlier this offseason.
King was second on the Jayhawks in receiving yards last season, finishing with 30 receptions for 537 yards and one touchdown. King surprised Kansas fans when he elected to go pro. Fans saw potential in him, but they still projected him as unlikely to have his name called on draft day. He had graduated already, so it is possible he felt it was worth declaring and hoping for the best.
His scouting report points to a player with good size (6'3, 210 pounds), but lacking in top end speed and sharp route-running. You can view some other scouting reports at NFL Mocks and Pro Football Spot.
Bruce Ellington and Issac Blakeney are both dealing with leg strains, so this is a basic depth addition. Jim Tomsula mentioned the strains yesterday, and we have not heard anything new on either player's status. Additionally, Jerome Simpson missed a couple practices due to personal reasons. Trent Baalke said last night that Simpson could be back as soon as Wednesday.
