49ers fill out their 90-man roster with three signings

The San Francisco 49ers announced a slew of roster moves Monday afternoon, giving them a full complement of players on their 90-man offseason roster.

The Niners signed place-kicker Corey Acosta and receiver Mario Hull to three-year deals and offensive lineman Ben Gottschalk to a two-year contract.

In corresponding moves, the team announced it waived receiver Darius Davis, an undrafted rookie from Henderson State signed after the draft, and offensive tackle Chris Martin, who had signed a reserve/futures contract in December after spending the last three weeks of the season on the team’s practice squad.

Acosta was undrafted out of Southern Mississippi, where he scored 201 points with 43 field goals, including 19 as a senior.

The 6-foot-1, 200-pound Hull also was undrafted, out of Rice, and had 61 catches for 901 yards and eight touchdowns in three seasons. Last year, he had 32 receptions for 621 yards and his eight TDs.

Gottschalk, a 6-5, 293-pounder who was an undrafted free agent of the Kansas City Chiefs out of SMU last year, spent a week on their practice squad early last season before being waived and signed with the Tampa Bay Buccaneers this April. He was waived by the Bucs in late May.
