TAMPA — Even without its coach, Plant rolled over Robinson in the battle of South Tampa.
Allen Sampson took the opening kickoff back 97 yards and the Panthers cruised during a 42-0 win in the 49th meeting between the two schools.
Coach Robert Weiner was suspended following his ejection from last week's 30-7 victory over Jefferson.
Wide receiver coach T.J. Lane filled in for Weiner in what appeared to be a seamless transition as Plant's offense clicked and its defense was impressive.
"This win meant a lot to us because we were playing without our head coach," tight end Orson Charles said. "It was a bit different because you could tell Coach Weiner wasn't calling the plays."
Although the calls were coming from a different source, Robinson (2-8) struggled to find an answer for Plant's aerial attack.
Quarterback Phillip Ely threw for 205 yards and three scores with Charles and Sampson as his main targets. Charles caught seven passes for 95 yards and two scores while Sampson added 84 yards and a touchdown on six catches.
Robinson totaled just 9 yards of total offense, including 16 runs for minus-47 yards as the Panthers recorded their second shutout of the season.
Beau Hume returned an errant Knight pass 21 yards for a score, the interception was his second of three for the Panthers (8-1).
"Our defense is always big, they've been playing well every game," Sampson said. "I don't think they get enough credit for what they do."
