49ers signed Auburn S Jermaine Whitehead.
Whitehead (5'11/197) was a three-year starter in the Tigers’ secondary, amassing nine INTs and contributing on special teams throughout his college career. Although Whitehead ran 4.59 at the Combine, he excelled in the vertical (37") and broad (10'8") jumps and was a top performer in the three-cone and shuttle drills. A quick-twitch mover who holds his own in run support, Whitehead’s draft stock was affected by clashes with the Auburn coaching staff, his smallish build for a safety and questionable on-field instincts.
