SANTA CLARA -- The 49ers cut a starting guard from 2015, Jordan Devey, to make room for the team's rookies who are gathering this week for a minicamp.
Devey started the first nine games at right guard last season after the 49ers acquired him in August in a trade from New England. He later was replaced by Andrew Tiller and Erik Pears at the position. The 49ers also released kicker Corey Acosta, running back Kendall Gaskins and quarterback Dylan Thompson.
The 49ers added a guard in the first round of the draft, Stanford's Joshua Garnett, and drafted two tackles, John Theus and Fahn Cooper, who also are capable of moving inside. Tiller, Marcus Martin, Brandon Thomas, Zane Beadles and Pears also will compete to play guard this year. The 49ers also are expected to add undrafted rookie guard Blake Muir from Baylor to their roster.
Acosta, meanwhile, kicked well last offseason and preseason.
Never miss a local story.
But Derius Swinton, the 49ers' new special teams coordinator, seems to like Liberty kicker John Lunsford, whom the 49ers added as an undrafted free agent. Swinton attended and ran Lunsford's pro-day workout in Virginia in March.
The 49ers must think about an heir to regular kicker Phil Dawson, who turned 41 in January. Lunsford made 48 of 79 field-goal attempts in four seasons at Liberty (60.8 percent) but was only 13 of 24 last year (54.2 percent). He was 4-6 from 50 yards and beyond and he made a 60-yard field goal in 2014.
“Well it was a fun ride, but looks like my future is elsewhere,” Acosta wrote on Twitter. “Thanks 49ers for the opportunities and I look forward to wherever is next.”
