General manager John Lynch said this week that the 49ers have scheduled the 30 pre-draft visits they are allotted but that only one prospect, Alabama linebacker Reuben Foster, has arrived so far.
Here's the list of visitors, which likely will grow in coming weeks as those meetings are made:
DE Johnathan Calvin, Mississippi State.
A late bloomer, Calvin led Mississippi State last season with 11 1/2 tackles for loss and seven sacks to go along with 55 tackles The 6-3, 269-pound defensive end also led the SEC with two blocked kicks. Calvin seemed to get better as the year went on and he projects to the rush or "elephant" defensive end spot with the 49ers.
