The 49ers on Tuesday signed tight end Garrett Celek, who was scheduled to become a free agent next month, to a four-year contract extension.
Celek, 27, began his career in 2012 as an undrafted free agent who specialized in blocking. He since has become more of a dual threat and last year had a career-high 19 catches for 186 yards and three touchdowns. He went on injured reserve Dec. 8 because of an ankle injury.
New coach Chip Kelly likely is eyeing Celek and Vance McDonald as his top tight ends. The 49ers have two others, 2015 draft picks Blake Bell and Rory Anderson, on the roster, plus late-season addition Je’ron Hamm.
Celek’s older brother, Brent, played the last three seasons under Kelly with the Philadelphia Eagles. Brent Celek had 27 catches for 398 yards and three touchdowns last year.
