Mizzou Basketball Head Coach Mike Anderson added to his front court in the 2009  spring signing period, with the signing of 6-foot-9 shot-blocker Jon Underwood (Phoenix, Ariz. / Princeton Day Academy) and 6-foot-7 power forward Tyler Stone (Memphis, Tenn. / Central) to National Letters of Intent on Monday.  

Underwood led Princeton Day Academy in Lanham, Md., to a 33-3 overall record and a #7 national ranking in the final National Private School Athletic Association (NPSAA) polls, while Stone was an All-City pick in talent-rich Memphis after helping Central High School to a 25-4 overall record. 

In a statement released by the University, Head Coach Mike Anderson said "I’m excited to welcome both Jon and Tyler to the Missouri Basketball family.  We addressed some of our basketball needs with these two young men and we also added two quality individuals to our locker room. They fit what we are looking for with regards to size and athleticism and they join both Mike Dixon and Keith Dewitt to give us another good recruiting class." 

Underwood led his team to a pair of national title game appearances by averaging 18 points, 11 rebounds and eight blocked shots per contest for Head Coach Van Whitfield’s club. The athletic 190-pound forward was named to the All-Tournament teams at the National Athletic Christian Association Championships in Dayton, Tenn., and the National Christian School Athletic Association Championships in Erie, Pa. He also earned All-Tournament honors at the Nike iS8 Tournament in New York and at the Crossin Memorial Classic in Plymouth, Pa.

A 6-foot-7, 225-pounder, Stone brings a versatile game after starting two seasons for Head Coach Andre Applewhite at Central High School, where he averaged 15 points and eight rebounds as a senior. An All-City and All-Region selection by the Memphis Commercial Appeal , Stone was named the District 16 AAA MVP and is considered a rising standout in the Memphis area after recently turning just 17-years-old.
