Vikings General Manager Rick Spielman joined the wave of NFL front offices trading on-the-bubble talent for a late-round draft pick before Saturday's 3 p.m. deadline to trim rosters from 90 to 53 players.

Guard Danny Isidora was traded to the Miami Dolphins for a 2020 seventh-round pick on Friday.

Isidora, the 25-year-old Weston, Fla. native, was a fifth-round pick in 2017 out of the University of Miami. He was active for 21 NFL games the past two seasons and made three starts.

He returns home to Florida, and the Vikings get a pick for a player they were probably going to release Saturday. Seven teams, including the Patriots, Packers and Colts, have executed nine trades this week with the same approach of securing a late-round pick for a castoff.

By adding a seventh-round pick, the Vikings could have upward of 11 draft picks for next spring should they be awarded the maximum four compensatory picks for lost free agents that included defensive tackle Sheldon Richardson, running back Latavius Murray, and guards Nick Easton and Tom Compton.

Isidora was an odd man out in the Vikings' interior line makeover that has new starters at every position and new depth in guard/tackle Dakota Dozier and guard Dru Samia. Isidora started Thursday's preseason finale in Buffalo, but he and Brett Jones played the fewest snaps (26) of any offensive lineman.

Cuts begin

The Vikings began trimming the roster Friday afternoon, informing receiver Alexander Hollins, linebacker Reshard Cliett, defensive tackle Curtis Cothran, tackle Nate Wozniak and defensive end Anree Saint-Amour that they'll be placed on waivers, according to league sources.

Wozniak, the former Gophers tight end turned offensive tackle, was signed earlier this month after injuries thinned the Vikings' tackle depth.

The Vikings also plan to let go safety Derron Smith, running back DeAngelo Henderson and center Cornelius Edison, according to reports.

About 26 more moves need to be made ahead of Saturday's 3 p.m. deadline.
