Sterling Jenkins, a 6-foot-8, 305-pound offensive tackle from Baldwin High School near Pittsburgh, has signed a national letter-of-intent to play his college football at Penn State and will enroll at the university in January, a spokesman for the program said Monday.

Jenkins is the second incoming offensive tackle to sign a letter-of-intent this month with the plan to enroll early. Paris Palmer, who played for two seasons at Lackawanna College, signed on Dec. 14. Both players will be able to participate in off-season conditioning and spring practice.

Jenkins, who gave an oral commitment in May to coach James Franklin, is rated as a four-star recruit by numerous recruiting web site. Scout.com and ESPN.com ranked him as Pennsylvania's No. 1 player and he is listed in the top 10 among the nation's offensive line recruits.
