[UPDATE] Source: Patriots Cut QB Matt Flynn, Sign QB Ryan Lindley

The New England Patriots' quarterback depth chart was set in stone basically when the team traded Ryan Mallett to the Houston Texans prior to the 2014 season. Tom Brady is the clear-cut number one, Jimmy Garoppolo the clear-cut number two. Everyone else would automatically have no better standing than number three on the depth chart.

It turns out that the Patriots don't even have a number three right now after the team cut Matt Flynn today, according to ESPN's Dianna Russini:

The 30-year old Flynn was signed by the Patriots as a free agent on June 11 and naturally became the team's number three quarterback. However, according to Russini, Flynn injured his hamstring prior to training camp and was subsequently placed on the Non-Football Injury list. His hamstring apparently never healed and thus Flynn was unable to come off the list. This caused the team to cut its third-string quarterback today.

With Flynn gone, the Patriots only have two quarterbacks left on their roster and are a prime candidate to add another one prior to Thursday's preseason opener against the Green Bay Packers, coincidentally Flynn's old team. Overall, the team now has 89 players on its roster.

UPDATE: According to Field Yates, the Patriots have quickly filled Flynn's spot by signing quarterback Ryan Lindley.

The 26-year old Lindley was a sixth round pick by the Arizona Cardinals in 2012 and started the team's 2014 wild card playoff loss against the Carolina Panthers in which the team broke the record for fewest total yards of offense in a playoff game (77). Including the playoffs, he played in ten games over the course of his career, throwing three touchdowns and 13 interceptions.
