Prospect names have been discussed between the two teams.
Utley cleared waivers on Tuesday night and can now be traded to any team before the Aug. 31 waiver trade deadline, if he waives his no-trade clause.
Giants second baseman Joe Panik is on the disabled list with a back injury and has not resumed baseball activities. Kelby Tomlinson was recalled from Triple A and has split time with Ehire Adrianza in the infield.
Utley, 36, was activated from the 15-day disabled list last week after missing 37 games due to right ankle inflammation. In his return, Utley is 5-for-13 with three doubles, three RBIs and three runs scored in four games. On the season, he is batting .190 with four home runs, 28 RBIs and a .557 OPS over 69 games.
Utley, now in his 12th season with Philadelphia, is expected to earn $15 million this season and also has a $15 million club option for 2016 that includes a $2 million buyout. The option vests if Utley reaches 500 plate appearances this season. Utley has 267 plate appearances through Wednesday.
