Hollister (hamstring) was ruled out for Monday's game against the Bills, Doug Kyed of NESN.com reports.
Hollister was a limited participant at practice this week, but the Patriots apparently didn't see enough to hand him the questionable tag. The 24-year-old will miss his second straight game, leaving Dwayne Allen to serve as No. 2 tight end with Rob Gronkowski (back) listed as questionable, although he expects to play.
