Blacksburg, VA -- Derrick Knight rushed for 197 yards on 38 carries and scored two touchdowns, as Boston College upset No. 12 Virginia Tech, 31-27, at Lane Stadium.

Knight, the Big East Co-Offensive player of the week, is now Boston College's all-time leading rusher. With 3,603 rushing yards he surpassed Mike Cloud.

Quarterback Paul Peterson threw two touchdown passes, including a 64-yarder to Larry Lester with 4:40 remaining in the game to give the Eagles the lead for good. On 3rd-and-10 from the Boston College 36-yard line, Peterson found Lester, who made a one-handed catch and broke free from the safety for the game-winner. Lester caught two passes for 79 yards.

On the day Peterson was 15-for-28 for 232 yards with two interceptions for the Eagles (7-5, 3-4 Big East), who won for the first win in Blacksburg since 1995 and solidified their bowl hopes.

Kevin Jones rushed for 165 yards on 24 carries, while scoring three touchdowns for Virginia Tech (8-3, 4-3). He also caught three passes for 57 yards.

The Hokies, a one-point overtime winner last week at Temple, have lost three of their last five.

Tech quarterback Bryan Randall played the majority of the contest due to the ineffectiveness of Marcus Vick and finished the day with 176 yards on 12-of-23 passing.

The Hokies trailed 24-20 heading to the fourth quarter and Tech turned the ball over on downs at the Boston College 30 with just over nine minutes remaining, but got the ball back and needed only three plays to take the lead.

Randall hit Ernest Wilford for a 52-yard gain to the Boston College 16-yard line and Jones did the rest. He ran for three yards to the 13 and carried it into the end zone from there to give Tech a 27-24 lead with 6:36 to play.

It took the Eagles just five plays in less than two minutes to answer with the Lester touchdown reception to take the lead for good at 31-27.

The Hokies couldn't answer and punted it away with 3:18 to play, hoping for a quick stop to get the ball back. Knight, however, spoiled that strategy with a 60-yard run on second down to set up a 29-yard field goal by Sandro Sciortino to give the Eagles a seven-point edge with 1:42 left.

Cedric Humes then fumbled the ensuing kickoff and Boston College recovered to seal the contest.

The Hokies turned the ball over on the first play of the game. Randall completed a pass to Wilford, who fumbled the ball at the Virginia Tech 42-yard line. Eight plays later, Sciortino kicked a 25-yard field goal to give Boston College a 3-0 lead just 2:36 into the contest.

Tech then marched down the field and converted a 22-yard field goal by Carter Warley to tie the game with 8:27 left in the opening quarter. The key play was a 55-yard pass from Randall to Jones on a 3rd-and-8 from Hokies' 35-yard line.

It took less than a minute for Boston College to regain the lead.

Will Blackmon took the ensuing kickoff from his own one-yard line and raced 53 yards to the Hokies' 46. On 2nd-and-9, Peterson connected with Knight for a 37-yard gain to the nine-yard line. Knight's three-yard touchdown run then gave Boston College a 10-3 lead with 7:29 left in the first.

The Hokies then scored 14 unanswered points to take a 17-10 lead.

Jones took a handoff on the Hokies' 38-yard line, eluded several tacklers and sprinted right up the middle of the field for a 62-yard touchdown run and the game was tied again at 10-10. The touchdown run came with exactly six minutes to go in the first.

The Eagles then threatened to again move in front, but Peterson was picked off by Jimmy Williams at the Tech five-yard line and the return gave the Hokies a first down at their own 33.

Randall directed a 67-yard drive that Jones capped with a one-yard touchdown run on the first play of the second quarter to give Tech a 17-10 lead.

Another interception gave the Hokies a chance to extend the lead, as Peterson was picked off by Eric Green, who raced 31 yards to the Boston College 17. Vick then took over at quarterback and could not produce a first down, and a 35-yard field goal attempt by Warley was blocked with 11:14 left in the half.

The Eagles closed out the first half scoring 14 unanswered points.

Knight's four-yard touchdown run knotted the game at 17-17 with 2 1/2 minutes remaining.

Boston College got the ball back just under a minute later and needed only 56 seconds to score again, as Peterson hit Grant Adams with a 16-yard touchdown pass to make it 24-17 heading to the intermission.

Adams caught four passes for 94 yards.

Early in the third quarter, the Eagles looked to extend their lead, but after a holding penalty on a field goal attempt pushed the Eagles backed 10 yards, Sciortino's 44-yard attempt was wide left.

The Eagles held Tech on their next possession only to give the ball back on the ensuing punt. The Eagles' Nathan Hasselback fumbled the punt return and Tech's Williams recovered on the BC 18-yard line.

Randall threw three straight incomplete passes and Warley converted a 35-yard field goal to cut the Eagles' lead to 24-20 with 8:59 to go in the third.
