CARBONDALE, Ill. -- Jonathan Grimes ran for 133 yards and three touchdowns in pacing William & Mary to a 24-3 victory over Southern Illinois on Saturday in a Football Championship Subdivision playoff quarterfinal.
R.J. Archer passed for 192 yards for the Tribe (11-2) in snapping the Salukis' 11-game winning streak, dating to a loss to Marshall in the season opener.
The Tribe will face Villanova in a semifinal next Saturday.
Southern Illinois (11-2) had entered the game with the FCS' fourth-best rushing attack, averaging 231 yards a game, and ranked third nationally in scoring at nearly 37 points a game.
But the Salukis mustered just 84 yards on the ground against the FCS' top rushing defense, giving up just 50 yards a game.
Southern Illinois' Deji Karim, who by averaging 138 rushing yards a game ranked second in the FCS, managed only 27.
Montana 51, Stephen F. Austin 0
Andrew Selle threw for three touchdowns and ran for another, and Montana took advantage of 10 Stephen F. Austin turnovers.
Montana (13-0) will host a semifinal game against the winner of Saturday night's contest between Appalachian State and Richmond.
Seven of the turnovers by Stephen F. Austin (10-3) came in the first half. The Grizzlies capitalized on four fumbles and three interceptions to build a 38-0 halftime lead.
Chase Reynolds had two TD runs, and Brody McKnight kicked three field goals.
Defensive tackle Tyler Hobbs lead the Montana defense with an interception and two fumble recoveries.
Villanova 46, New Hampshire 7
Angelo Babbaro ran for 148 yards and two touchdowns to lead Villanova to a win over New Hampshire.
Villanova (12-1), which has won seven games in a row since a 28-24 loss to New Hampshire this season, advances to host William & Mary in the semifinals.
Villanova's defense was stout against the New Hampshire (10-3), holding them to 84 yards total on offense for the game. On the first play from scrimmage, Villanova defensive back John Dempsey returned a fumble 4 yards for a touchdown en route to the easy win.
Villanova, which collected six sacks, held New Hampshire without a first down until 6:31 left in third quarter.
Chris Whitney attempted only five passes, completing three for 44 yards and a touchdown run for Villanova.
Appalachian State 35, Richmond 31
The Mountaineers (11-2), who had won three straight national championships before getting knocked out by the Spiders in last year's quarterfinals, exacted their revenge after Richmond had taken the lead on a remarkable strip and fumble return by Eric McBride with 3:26 left.
On the play, the Spiders punted and Travaris Cadet fielded it inside his 10. While he was trying to return it, McBride stripped the ball and took it 8 yards into the end zone -- a stunning play that gave Richmond a 31-28 lead.
But the Mountaineers drove 70 yards before Edwards rifled the pass to Cline in the end zone, just past a diving defender's reach.
