Spell became the first commit to Penn State's recruiting class of 2027.
Dawkins made the watch list for the Allsate Wuerffel Trophy, while Singleton was recognized by the Paul Hornung Award.
Jennings committed just hours after class of 2025 three-star defensive lineman Yvan Kemajou.
Both players are suspended to deal with a "personal matter," per a Penn State Athletics spokesperson.
Kemajou is ranked as the 12th-best player in Maryland, per the 247Sports Composite rankings.
Both Carter and Wormley had already earned preseason recognition.
