The SaberCats sent veteran quarterback Aaron Garcia to Orlando for wide receiver Amarri Jackson on Thursday.
The Predators also acquired offensive lineman Devin Clark in the deal.
Garcia had a six-touchdown, five-interception performance in Friday's 69-47 loss to Seattle. Afterward, he was placed on recallable assignment.
"Amarri brings a great deal of size and athleticism to our receiving corps," SaberCats coach Darren Arbet said.
A three-year AFL veteran, Jackson has 21 catches for 291 yards and six touchdowns in three games this season.
Also, Russ Michna, who was home in Chicago last weekend, practiced again with the SaberCats. The former Chicago Rush quarterback will be on the field when San Jose plays at New Orleans on Saturday at 5 p.m.
"It all happened pretty quickly," said Michna, who has been assigned to San Jose on a two-year contract. "I received a phone call, told my wife I was leaving and got on a plane."
Rebecca Woodberry, who transferred from Nebraska after the fall semester, received clearance from the NCAA to compete for the Spartans starting in the 2013-14 school year. She'll have two seasons to compete for the Spartans.
Jockey Russell Baze, who won the first race (two-furlong dash for 2-year-old fillies) with La Tonga and placed second in the second race aboard Epic Electorate, took off his final three mounts due to a "minor back strain," said the track physician at Golden Gate Fields.
