A look at the former Patriots coaches and players on the Kansas City Chiefs and San Francisco 49ers heading into Super Bowl LIV.

SAN FRANCISCO 49ERS

Quarterback Jimmy Garoppolo: Drafted by New England in Round 2 of the 2014 NFL Draft, Garoppolo appeared in only 17 games for the Patriots before being dealt to the 49ers on Halloween 2017.

Wide Receiver Jordan Matthews: A free agent signing at the time, Matthews spent barely four months with New England from April to August 2018. He was released with an injury settlement after suffering a hamstring problem during training camp.

Kicker Robbie Gould: The Penn State product began his productive NFL career as an undrafted rookie with New England in 2005, but was released during the preseason.

Wide Receivers Coach Wes Welker: After arriving in Foxborough via a trade with the Dolphins in 2007, Welker earned five Pro Bowl nods, was named a first-team All-Pro twice, and led the NFL in receptions three times during his six seasons with the Patriots.

General Manager John Lynch: The 2020 Pro Football Hall of Fame finalist failed to make the final Patriots roster after signing during training camp in 2008 preseason. This came after a stellar career with the Tampa Bay Bucs and Denver Broncos.

KANSAS CITY CHIEFS

Defensive Tackle Mike Pennel: A veteran free agent signing last spring, Pennel was eventually released following the third preseason game.

Defensive Line Coach Brendan Daly: Joined the Chiefs' staff in 2019 after serving the previous four seasons as New England's defensive line coach since 2015.

Quarterbacks Coach Mike Kafka: Signed a future contract with the Patriots in January 2013. Took part in practices that spring before being released in June.
