Purdue has signed 7-foot-2 center Isaac Haas to a national letter of intent.
The news comes one week after incoming freshmen could first sign with colleges - and one week after coach Matt Painter promised to add a center to his recruiting class.
Haas averaged 18.5 points, 11.0 rebounds and 4.5 blocks at Hokes Bluff High School in Alabama last season.
He joins a class that includes forwards Vince Edwards and Jacquil Taylor and guard Dakota Mathias.
