Coming off the bye week, the San Francisco 49ers have shuffled their practice squad.

Out are fullback Jahuu Caulcrick and linebacker Erik Bahktiari, who will be replaced by running back DeShawn Wynn and wide receiver Lance Long.

Long (5-11, 186) was recently released from the Jacksonville Jaguars practice squad. An undrafted free agent out of Mississippi State, Long split last season with the Arizona Cardinals and Kansas City Chiefs.

Long hauled in 20 passes for 178 yards in a seven-game stint with the Chiefs.

Wynn was a seventh-round pick (228th overall) out of Florida by the Green Bay Packers in 2007.

In 20 career games, Wynn has gained 332 yards on 64 carries with five touchdowns, and has added 14 receptions for 122 yards as a receiver out of the backfield. Wynn also two tackles and a fumble recovery on special teams.

Wynn spent four games this season with the New Orleans Saints.
