The Patriots promoted fullback Joey Iosefa from the practice squad today and waived linebacker Eric Martin with an injury designation.
Iosefa had been on the practice squad since Oct. 21 and will aid Brandon Bolden and James White in the running game tomorrow against the Titans. The Buccaneers' seventh-round pick in the 2015 draft had 2,218 rushing yards and 21 rushing scores at Hawaii, so he is capable of running the ball if called upon.
Martin suffered a concussion this week, but it took a while to diagnose. He was absent from Thursday's practice with an illness, but the team determined yesterday that it was actually a concussion.
