Richardson missed Golden State’s third straight win Sunday, 104-94 over the Sacramento Kings, because he traveled to Michigan for personal reasons. As of Monday, Warriors officials said they weren’t sure when he would return to the team.
Foyle sat out the game with the flu and is a game-time decision for Wednesday.
Without the two starters, Troy Murphy picked up the slack by scoring 29 points and grabbing 14 rebounds as the Warriors moved within one victory of their season-best win streak, set from Dec. 22-29.
Richardson was named the Western Conference player of the week on Monday after averaging 24 points, 10.3 rebounds and 4.7 assists in three games last week.
“Different guys have to step up when guys are out,” Murphy said. “Jason missed a bunch of games earlier this season with a sprained ankle and we didn’t win one of them. We had to make up for that poor showing.”
Rookie center Andris Biedrins made his first career start in place of Foyle and had 12 points and 10 rebounds for the Warriors.
“We lost our best player Jason and Adonal, so Andris stepped up and played a great 30 minutes,” said Golden State’s Zarko Cabarkapa, who added 17 points off the bench. “Everybody played well. The last couple of weeks we’ve played great every game. We know we can win.”
Golden State has had trouble winning against Dallas, losing 22 of the last 24 meetings.
The Mavs won their third straight on Monday, 103-86 over the New Orleans Hornets.
Dirk Nowitzki scored 25 points for Dallas, which has won five of six.
That includes a 2-0 mark since Avery Johnson took over permanently for Don Nelson as head coach.
This will be Johnson’s first game in that capacity against the team with which he played his last NBA game. The former point guard appeared in 46 games for Golden State last season before signing this summer with Dallas, only to end up on the bench as an assistant to Nelson.
Monday’s win saw the Mavs hold an opponent below 40 percent from the field for the 15th time this season. Dallas is unbeaten in those games as Nelson— and Johnson when he was an assistant—tried to convince what had been an offensive-minded team to pay more attention to the defensive side.
“Overall, this game wasn’t necessarily about playing our opponent,” Johnson said. “It was about improving our system. It was a good win for us.”
