The 49ers promoted former Cal wide receiver Chris Harper to the team’s active roster on Tuesday.
To make room for Harper on the roster, the team released wide receiver Keshawn Martin, who appeared in two games, handled two kickoffs and fumbled away one of them.
The 49ers signed wide receiver Mose Frazier to the practice squad to take Harper’s spot.
Harper was active for the 49ers’ Week 1 victory over the Los Angeles Rams. He was waived the next day but re-signed to the team’s practice squad.
In his three seasons at Cal, Harper caught 163 passes for 2,030 yards and 13 touchdowns. He appeared in five games with the New England Patriots last season as a rookie, catching one pass for 6 yards.
Frazier entered the NFL with the Denver Broncos in May as a undrafted rookie from Memphis. He has spent time with the practice squads of the Broncos and Buffalo Bills this season.
