Patrick Chung and Brandon Bolden appeared to be on the roster bubble in August, but the New England Patriots safety and running back do not appear to be going anywhere now.

As Field Yates of ESPN first reported Friday morning, the team has signed Chung to a three-year extension through 2017 worth up to $8.2 million with $3.4 million guaranteed.

Bolden has also signed a two-year, $2.32 million extension through 2016, according to Yates.

Both were impending free agents on a 53-man Patriots roster consisting of 17, with Chung unrestricted and Bolden restricted. And both have illustrated their value to the Patriots over the course of the regular season.

Chung, 27, returned to New England last March after spending exactly 364 days of his three-year, $10 million deal with the Philadelphia Eagles.

“I don’t have any expectations,” Chung said in a conference call after rejoining the team in April. “Whatever Bill [Belichick] needs me to do, this team, I’m going to do it. Regardless if it’s special teams or it’s defense, whatever my role is here, I’m OK with that.”

The 2009 second-round Patriots draft pick went on to carve a role in his second stint with the team, spending 857 defensive snaps on the field over 16 games, and grading out among the top dozen safeties in the league, according to Pro Football Focus. Chung recorded 85 combined tackles, one interception and four passes defensed along the way, serving as a starter next to free safety Devin McCourty, who will be a free agent at season’s end.

“Thank you to the Patriot organization for giving me a 2nd chance and keeping me around for a couple more,” Chung said via Twitter Friday.

Bolden, 24, first joined the Patriots organization as an undrafted rookie out of Ole Miss in 2012. The 5-foot-11, 220-pound running back has since played in 38 games, rushing for 634 yards and six touchdowns.

Bolden totaled 28 carries for 89 yards and two catches for eight yards in New England’s offense this season, yet he has established himself as core contributor on special teams.

He’s totaled six tackles as well as a blocked punt for the Patriots in 2014. He’ll get the chance to do so for the next two.

New England now has five running backs under contract for next season in LeGarrette Blount, Jonas Gray, James White, Tyler Gaffney and Bolden. Stevan Ridley and Shane Vereen are scheduled to become free agents.
