Linebacker Navorro Bowman had three sacks and an interception to pace a stellar Penn State defense that held Temple to 138 yards and 10 first downs.
The 81-year-old Paterno walked slowly and gingerly at times along the sideline in the first half as Penn State built a 31-0 lead, then moved upstairs alongside his assistants in the second. He had been complaining this week of a sore right leg.
"If I stand on it too long, I hurt it," Paterno said. "I'm probably babying myself."
The Nittany Lions were sluggish in the first quarter, held scoreless in the opening frame for the first time this season. Penn State fumbled twice in the quarter, recovering both times. Things changed in a hurry.
Green had a 27-yard run to get Penn State to the Temple 20 before Clark connected with Brett Brackett over the middle, barreling over the Owls' Dominique Harris as he crossed the goal line to give Penn State a 7-0 lead with 14:27 left in the second quarter.
Evan Royster had a 32-yard TD run about 3:30 later. Temple thought it had regained momentum after Travis Shelton returned the ensuing kickoff 74 yards to the Penn State 26.
But the Nittany Lions got an interception. Three plays later, Clark ran in from 11 yards to put the Nittany Lions up 21-0.
Jake Brownell's 25-yard field goal in the third quarter gave the Owls their only score. Chester Stewart finished 16-for-30 for 116 yards and three interceptions in relief of starter Adam DiMichele, who was knocked out of the game because of a right shoulder injury. Penn State's offense continued to click against overmatched opponents. The Nittany Lions scored 40 or more points for the first four games in a season for the first time in Paterno's 43 seasons as head coach.
Paterno has complained of soreness in the right leg after kicking a ball in practice several weeks ago. He was on the sideline the entire game for the first three games this season, but monitored practices this week from a golf cart.
Paterno also sat in the press box the final two games of the 2006 season, including the Outback Bowl, as he recovered from a left knee injury.
