Those cardiac conference cousins of the Big Sky were at it again on Saturday.

First, Montana State made a last ditch touchdown drive to tie its game with Portland State and eventually win in overtime, then Montana blocked a field goal to keep its game with Eastern Washington from going into overtime.

Helena's Shane MacIntyre did the trick this time for the Grizzlies as he laid his body out to reject EWU's 28-yard attempt in preserving UM's 31-28 win. Montana won last week when Jonny Varona blocked an Idaho State field goal in 24-22 win.

The seesaw battle had the Grizzlies trailing 10-0 in the first quarter, leading 21-13 in the second half, tied at 21, then leading 31-21 late in the fourth quarter before EWU scored and then went for the tie.

The Bobcats game had a comeback within the comeback as quarterback Travis Lulay looked lost for the afternoon after taking a severe blow to the head in the second quarter. After team doctors checked him out at halftime he came back in the second half and threw for a whopping 292 yards in the second half and overtime alone.

Last week MSU trailed 17-0 in the third quarter before scoring 20 unanswered points, including E.J. Cochrane's game-winning 44-yard field goal as time ran out.

MSU trailed 14-3 at halftime and 21-10 in the second half on Saturday, in a game between the top two defenses in the league. Justin Domineck drove across the goal line as time expired to send the game to overtime. The Bobcats finished with 471 yards to 386 for the Vikings.

Domineck and UM's Lex Hilliard both ran for three touchdown runs. Domineck's came from three, one and 17 yards, while Hillard's were from the 16, eight and two-yard lines.

The wins move UM and MSU into a first place tie in the league standings at 3-0. The Bobcats are 4-2 overall, while the Grizzlies stand at 6-1. Eastern Washington fell into second place at 3-1 in the league.

In other Big Sky action, Sacramento State ended a long scoring drought in fine fashion, posting a 31-12 win over winless Weber State.

The Hornets got 114 yards rushing and a pair of touchdowns from Tyronne Gross and the defense harassed WSU quarterback Kyle Bauer into a sour 12-for-37, 155 yard, four interception day.

Northern Arizona got back in the win column in a non-conference game against Division II Western New Mexico. The Lumberjacks' 34-14 win comes on the heels of a tough 45-14 loss last week to Eastern Washington.

NAU built a 34-6 lead after three quarters behind the passing of Jason Murietta, who threw for four TDs, and the running of Roger Robinson. NAU may have made the game more of a romp had it not committed 14 penalties for 136 yards. It finished with 414 yards of total offense and forced four turnovers.

Idaho State did not play this week. Next week is a bit of a slow one for the state's Big Sky teams. The Bobcats host a non-conference game against South Dakota State, while the Grizzlies are idle. Eastern Washington is at Weber State, Sacramento State is at Idaho State, and Northern Arizona hosts Portland State.
