Eligible to return on Friday, Tulowitzki took batting practice and live ground balls at Coors Field on Tuesday and will begin an injury rehab assignment on Wednesday.
According to the update, Tulowitzki has 1,200,256 votes to Furcal's 1,183,096.
Gonzalez is surging, going into Tuesday's opener of a three-game series with the Athletics leading the NL with 48 runs and ranking second in home runs (16) and RBIs (48), to go with a .326 batting average that was seventh in the league.
Last week, Gonzalez ranked 13th among outfielders, but he has moved up to 10th with 728,903 votes. The Dodgers' Matt Kemp leads at 2,589,464, and the next two starters -- if voting ended today -- are the Cardinals' Carlos Beltran at 1,782,831 and the Brewers' Ryan Braun at 1,553,356.
Other than Tulowitzki, who was invited to play in the All-Star Game the last two years and started last year with Reyes out with an injury, and Gonzalez, who is hoping for his first trip, no Rockies player ranks in the top five in any infield positions or among the top 15 among outfielders.
