The Patriots have just announced that Rodney Harrison has been placed on injured reserve, ending his 15th NFL season. Harrison suffered an injury to his right leg -- reportedly a torn quadriceps -- on the final play of the third quarter Monday night against Denver.

Harrison is in the final year of his contract, and that coupled with his age -- he is 35 -- may mean that he has played his last down in the NFL.

Defensive back Antwain Spann has been elevated off the practice squad to the 53-man roster in Harrison's stead.

Also, C Dan Connolly and DB Mark Dillard have been signed to the practice squad.
