The 49ers added some muscle to their thinnest position at the moment, strong safety, by signing five-year veteran J.J. Wilcox, to a one-year deal.
ESPN's Adam Schefter first reported the news on Wilcox, who has started 39 regular season games since he was a third-round pick for the Dallas Cowboys in 2013. The 49ers created a roster spot Monday by releasing cornerback Trovon Reed.
The 49ers have a promising, young starter at the position in Jaquiski Tartt. However, the next three players listed there are injured and won't be back until training camp.
They are sixth-round pick Marcell Harris, who suffered an Achilles tear at the University of Florida last year, and Don Jones and Chanceller James, both of whom suffered ACL tears a year ago.
