MINNEAPOLIS (AP) The Minnesota Vikings have kept undrafted rookie Taylor Heinicke as their third quarterback and underdog cornerback Marcus Sherels for the fifth straight season.

The NFL's roster reduction deadline for the regular season was Saturday, when the Vikings acquired offensive lineman Jeremiah Sirles in a trade with San Diego and released 22 players to reach the 53-player limit.

With Teddy Bridgewater entrenched as the starter and veteran Shaun Hill on board this year as the backup, the Vikings weren't a lock to keep a third quarterback. Heinicke, after a record-setting career at Old Dominion, had a strong preseason.

The 5-foot-10, 175-pound Sherels was undrafted out of Minnesota in 2010. His career average of 10.5 yards per punt return is the best in Vikings history.
