Hackenberg will compete for the No. 2 quarterback job with Bryce Petty (knee) after Josh McCown was named the opening-day starter Monday, Rich Cimini of ESPN.com reports.
The Jets had what they called an open competition for the starting quarterback role during training camp, but McCown was always the favorite to win the position. With Hackenberg not playing nearly well enough during preseason games and in practice, McCown, who wasn't overly impressive in his own right, will get the Week 1 start. McCown, 38, doesn't have a ton of upside, and given his injury history it's not out of the question that Hackenberg could take over at some point.
