Zac Dysert, a four-year starting quarterback at Miami (Ohio) and a projected mid- to late-round draft prospect, visited Monday with the Broncos.

Peyton Manning and second-year apprentice Brock Osweiler are the Broncos’ top two quarterbacks.

The team is expected to pick up its No. 3 and 4 quarterbacks either through the late rounds of the draft or from the undrafted free-agent crop.

The Broncos are not expected to select a quarterback in the first three rounds.

The 6-foot-3, 227 pound Dysert had 48 touchdown passes against 23 interceptions for nearly 6,996 yards in his junior and senior seasons combined. He has been getting quarterback training from former Heisman Trophy winner Chris Weinke, who played briefly for Broncos coach John Fox at Carolina.

Each NFL team can bring in up to 30 draft-eligible players, not including local prospects, to their facility for visits.

Leonhard signs with Saints. Veteran safety Jim Leonhard, who played sparingly for the Broncos last season, has signed a one-year contract with the New Orleans Saints.

Leonhard, 30, was a four-year starter for Baltimore and the New York Jets from 2008-11, but severe leg injuries the previous two years limited his playing to “dime” (six-defensive back) packages in his lone season with the Broncos.

The sure-handed Leonhard also served a designated fair-catch role on punts expected to land deep in the Broncos’ end.

Ball signs tender. Lance Ball, who has been part of the Broncos’ running back rotation the past three seasons, signed his $1.323 million tender as a restricted free agent Monday.

The salary doesn’t become guaranteed unless Ball makes the team’s season-opening roster.

Ball, who turns 28 in June, has exceeded the expectations of an undrafted player out of Maryland in 2008. Signed by St. Louis, Ball then had to grind through practice squads with the Rams, Indianapolis, Tennessee and the Broncos before sticking on Denver’s active roster for good in 2009.

He has 801 yards rushing on 4.2 yards per carry in his career.

Ball drew a $540,000 salary last year, and the jump to $1.323 million is another indication how the most recent collective bargaining agreement has bolstered the younger players who are considered in the “lower class” of the league’s economic structure. In exchange, the new system has allowed owners to significantly compress the open-market ceiling.
