Bartholomew (back) was placed on the reserve/PUP list Tuesday.
The rookie sixth-round pick out of Pittsburgh missed the entire training camp and will now sit out at least four games. Bartholomew put together a solid collegiate career but never surpassed 326 yards or four touchdowns in a season. Once he returns, he'll look to usurp undrafted rookie Benjamin Yurosek for the No. 3 tight end job.
