Toronto, ON (Sports Network) - Buck Pierce threw for 169 yards and two touchdowns, as the British Columbia Lions defeated the Toronto Argonauts, 24-20, to clinch a berth in the CFL playoffs.

Pierce completed 15-of-22 passes without throwing an interception, and Stefan Logan ran for a season-high 144 yards on 18 carries for the Lions (9-5), who have won five consecutive games. Logan also had three receptions for 13 yards and a touchdown, while O'Neil Wilson and Charles Roberts each scored once in the win.

Jamal Robertson ran for 139 yards and two touchdowns on 10 carries for Toronto (4-10), which has lost five straight games. Kerry Joseph threw for 228 yards on 13-of-27 passing, with two interceptions.

BC went back in front after surrendering a 10-point lead, as Pierce found Logan for a 10-yard touchdown with four minutes left in the third quarter. It capped a seven-play, 73-yard drive and gave the Lions a 24-17 advantage.

Mike Vanderjagt added a 30-yard field goal for Toronto with under four minutes to go in the game, but the Argonauts could not muster any more offense, and BC ran out the last two minutes to take the win.

BC got on the board in the first. Pierce led the team on a six-play, 67-yard drive, culminating in a 13-yard touchdown pass to Wilson with just over 11 minutes to play in the quarter.

Paul McCallum gave the Lions a 10-point lead early in the second quarter, nailing an 18-yard field goal with a little under 14 minutes to go until halftime.

Toronto got its first points less than a minute later, as Robertson scampered 75 yards to the end zone on the first play of the drive to cut the Argos' deficit to three.

But BC regained its 10-point advantage with about nine minutes to go in the half, as Roberts ran in for a one-yard score to make it a 17-7 game.

The Argonauts answered, as Robertson ran for his second long touchdown of the game -- a 48-yarder -- for a 17-14 halftime score.

The first score of the third was a 28-yard Vanderjagt field goal for Toronto, which tied the game at 17 with 8:53 to go in the quarter.
