In Morneau's place, Ben Paulsen will be making his major-league debut, playing first and batting sixth Monday night. Paulsen was hitting .291/.380/.524 with 24 doubles, 15 homers and 57 RBI for Triple-A Colorado Springs.
Morneau, 33, hasn't played since the All-Star break due to the stiff neck, so it obviously hasn't improved to the point that the Rockies thought it was worthwhile to keep him off the DL. Since he hasn't played since July 13, he could end up only being out another week.
Morneau is hitting .312/.345/.502 (121 OPS+) with 20 doubles, 13 homers and 60 RBI this season.
