49ers undrafted rookie WR Dontavia Bogan will miss the 2011 season after tearing his right ACL in practice.
Bogan also cracked a bone in his knee, which may delay surgery. He’s the second 49ers player to go down with an ACL injury in the first week of practice (blocking TE Nate Byham was the other). A possession receiver with kick return skills, Bogan was all-conference at South Florida last season.
