It appears rookie defensive lineman Solomon Thomas won’t make his on-field debut with the 49ers veterans until late July.
Thomas, the No. 3 overall pick from Stanford, was expected to participate during their mandatory minicamp Wednesday, which will include the final practice before training camp. However, the NFL rule that prevents players who attend colleges on the quarter system from participating in most of the offseason program should keep Thomas off the field Wednesday.
Per the NFL, Thomas can’t practice until Stanford’s final exams are over, and the last of Stanford’s final exams will end Wednesday night. The 49ers’ final practice is scheduled to start at 1:15 p.m. The 49ers haven’t confirmed Thomas can’t practice Wednesday.
The Panthers’ team web site noted rookie running back Christian McCaffrey, Thomas’ teammate at Stanford, can’t practice until Thursday when Carolina has its final practice of its mandatory minicamp. The 49ers will only have meetings Thursday before breaking until training camp.
Thomas and McCaffrey, who were only able to participate in their teams’ rookie minicamp in May, will reconnect in Week 1 when the 49ers host the Panthers.
