The Patriots have placed center Dan Koppen on injured reserve, ending his 2011 season. Koppen suffered a broken left ankle in the season-opening win over the Dolphins, an injury which was expected to keep him out for 10-to-12 weeks.
The 32-year-old Koppen had started 120 of 121 career regular season games since being selected in the fifth-round of the 2003 NFL Draft out of Boston College. Missing last Sunday’s game against the San Diego Chargers ended Koppen’s consecutive start streat at 65 games.
Veteran Dan Connelly replaced Koppen in the starting lineup. In addition to Koppen, the Patriots have placed defensive lineman Myron Pryor on injured reserve. A 2009 sixth-round pick out of Kentucky, Pryor has 35 tackles and a quarterback sack in 24 career games.
Replacing Koppen and Pryor on the 53-man roster are defensive tackle Landon Cohen and cornerback Phillip Adams. Cohen went to training camp with the Patriots, but was waived in August and claimed by the Seattle Seahawks, who released Cohen earlier this month. Adams was a 2010 sixth-round pick of the San Francisco 49ers who recorded 13 tackles, including nine on special teams, in 15 games as a rookie.
