New York Giants rookie mini-camp officially gets underway on Thursday as all participants report to East Rutherford. On-field evaluations and practices will then begin on Friday.

Although much of the focus will be spent on evaluating the Giants’ draft class and their horde of undrafted rookie free agents and tryout players, there will be a pair of veterans among the crowd.

The Giants will host both offensive lineman Michael Brewster and linebacker Nick Hagg on veterans tryouts over the weekend.

The 6-foot-3, 240-pound Haag was originally signed by the Indianapolis Colts as an undrafted rookie free agent in 2015, but only lasted throughout the preseason. Since then, he’s primarily played for the Spokane Empire of the Indoor Football League (IFL).

“I’m truly blessed,” Haag told The Spokane-Review. “When something like this happens, you remember all those who doubted you and said you couldn’t do it.

“That’s going to help immensely, just knowing exactly what’s expected out of NFL guys as far as meetings and what practices are like. I’m going to try to make the most of the opportunity.”

The 6-foot-4, 305-pound Brewster signed with the Jacksonville Jaguars as an undrafted rookie free agent in 2012. A year earlier, he had been projected as the premiere center had he declared for the draft, but he opted to return to Ohio State instead.
