SANTA CLARA, Calif. (AP) -- The San Francisco 49ers have signed offensive lineman Ben Gottschalk to a two-year contract while also adding kicker Corey Acosta and wide receiver Mario Hull on three-year deals.
San Francisco waived wideout Darius Davis and tackle Chris Martin on Monday, four days after wrapping up a mandatory minicamp at Levi's Stadium.
Gottschalk, an undrafted free agent last year, spent time on the Chiefs practice squad in 2014 then joined Tampa Bay on April 8 before being waived May 28.
Acosta is an undrafted free agent out of Southern Mississippi, where he kicked 43 field goals and had 201 points.
