With rosters needing to be cut down to 53 players on Saturday [VIDEO], a lot of roster turnaround was experienced over the past few days.

Quarterback play is always of the utmost importance to teams and a few signal-callers changed teams over the past couple days. Here are the quarterbacks who have found new addresses over the weekend.

AJ McCarron - Oakland Raiders

On Saturday, the Bills traded McCarron to the Raiders in exchange for a 2019 fifth round pick. He will serve as the backup to Derek Carr after the team released both Connor Cook and E.J. Manuel.

The 27-year-old was signed by Buffalo [VIDEO] in the offseason expecting to be the favorite to start Week 1 after the team moved on from Tyrod Taylor.

The Bills will instead begin the season with Nathan Peterman.

McCarron had his only three regular starts (plus one in the playoffs) come during the 2015 season.

Luke Falk - Miami Dolphins

The 23-year-old Falk was claimed off waivers Sunday by the Dolphins after he was cut by the Titans on Saturday. He was selected in the sixth round (199th overall) in the 2018 NFL Draft.

Playing collegiately at Washington State, Falk completed 68.3 percent of his passes for 14,481 yards, 119 touchdowns, and 39 interceptions during his four years.

Kevin Hogan - Denver Broncos

Despite trading for him in the offseason, the Redskins jettisoned Hogan from their roster on Saturday. The Broncos made a waiver claim for him on Sunday and subsequently released 2016 first round pick Paxton Lynch (Lynch will meet with the Bills on Tuesday according to NFL.com).

Turning 26 on October 20, Hogan appeared in eight games while starting one for the Browns in 2016-17. For his career, he has completed 60 of 101 passes (59.4 percent) for 621 yards, four touchdowns, and seven interceptions.

Christian Hackenberg - Cincinnati Bengals

Hackenberg was selected in the second round by the Jets in 2016. Despite the high draft choice used on him, he has yet to play in a regular season game. ESPN has reported that the Bengals have signed the quarterback to their practice squad.

This offseason, he was acquired by the Raiders who cut him less than a month later. He was then signed in mid-August by the Eagles, but as expected Hackenberg was released as he was short-term depth while Carson Wentz and Nick Foles were both on the mend.

In three seasons playing college football at Penn State, he completed 56.1 percent of his passes for 8,457 yards, 48 touchdowns, and 31 interceptions.
