According to sources close to ESPN Boston's Mike Rodak, the New England Patriots have made their third cut of the day, releasing veteran fullback Spencer Larsen.

Larsen was one of three fullbacks that were brought into training camp by the Patriots. Larsen played his entire four-year NFL career with the Denver Broncos, two of which came under the direction of Josh McDaniels.

On paper, Larsen's release is a shock, since he was given a two-year deal and a $250,000 signing bonus by the team. But as camp wore on, Larsen's stock began to fall. He's been battling some sort of injury throughout camp, and left and did not return in his preseason debut against the Buccaneers after sustaining a leg injury.

While it seemed almost a certainty that there would be a fullback on the Week One roster, the likelihood of it now seems bleak at best. With Larsen now gone and Tony Fiammetta out for the year with personal issues, military man Eric Kettani is the lone fullback remaining. But with the Patriots needing to make at least four more cuts to get to 75 by this afternoon and the 53-man deadline lurking on Friday, Kettani could still be a casualty to roster cuts.
