The 49ers on Saturday promoted tight end Je’Ron Hamm from the practice squad to be available for Sunday’s game against the Dallas Cowboys.
To make room for Hamm on the roster, the 49ers released running back DuJuan Harris for the third time this season.
The 49ers’ top two tight ends, Vance McDonald and Garrett Celek, are listed as questionable for Sunday’s game due to injuries sustained in last week’s game against the Seattle Seahawks.
McDonald (hip) left the game in the first half. His status against the Cowboys will likely be a game-time decision. McDonald and Celek (back) returned to limited practice this week.
Hamm, 24, spent time one game on the 49ers’ 53-man roster last season but did not appear in any games. He saw action in one game with Washington but did not catch a pass.
McDonald has five receptions in three games for 93 yards and two touchdowns. Celek has five catches for 52 yards. The 49ers' only other tight end is second-year player Blake Bell, who has one reception for 6 yards.
