Edelman, the team's fourth wide receiver and primary punt returner, has a broken foot that could require surgery, according to WBZ-TV. Edelman was moved to injured reserve on Tuesday.
For the season, Edelman had 21 receptions for 235 yards and three touchdowns. He was second in the NFL with a 15.5-yard average on punt returns.
The Patriots once had a mountain of options at wide receiver during training camp, but are now relatively thin at the position. The team cut Deion Branch last month and lost Greg Salas on a waiver claim by the Philadelphia Eagles. Stallworth fills a void, but the veteran hasn't been with a team since the Pats cut him in August.
