A MIX of disappointment and joy brought on Western Bulldogs captain Bob Murphy's tears after his team's preliminary final win over Greater Western Sydney, long-time teammate Matthew Boyd says.

Murphy has been sidelined since rupturing his left anterior cruciate ligament in round three against Hawthorn.

A player in the Bulldogs' three preliminary final losses from 2008-10, Murphy was at Spotless Stadium on Saturday night to see his team qualify for its first Grand Final since 1961 with a thrilling six-point win.

The 34-year-old could not hold back tears as he walked onto the ground to congratulate his teammates after the final siren.

Boyd, a teammate of Murphy's since 2003, told RSN927 on Tuesday morning the Bulldogs skipper had battled conflicting emotions after Saturday night's game.

"Bob and I embraced on the ground and he was visibly emotional, as he should be. There was tears of happiness, too, and I think that was part of his emotions," Boyd said.

"He was so happy for the group and he's been such a huge support throughout the whole time.

"It was a terrible way to finish his season early in the year with a knee injury and then to watch the team go on to make a Grand Final.

"It could be very difficult for some and clearly it's difficult for Bob at times, but he's nothing but supportive.

"He wants nothing but the best for this footy club."

Boyd, 34, remains uncontracted beyond 2016 despite making this year's All Australian team, having agreed to delay talks onm a new deal until after the finals.

Asked whether he would consider retiring if the Bulldogs win Saturday's Grand Final against the Sydney Swans, Boyd was non-committal.

"If we have a win this week I don't think I'll be thinking much about what's going on next week or next year," Boyd said.

"I think I'll just enjoy savouring the moment, but it's not a bad way to go out if you do go out winning a premiership."

Bulldogs coach Luke Beveridge said earlier this month Boyd would be offered a contract for 2017.
