The USWNT faces France on June 14 in Tampa, Florida and June 19 East Hartford, Connecticut.
Morgan and Long will join USWNT camp following the Thorns' match against Western New York on June 7 and will likely miss at least the match against the Washington Spirit on June 15 and could potentially play on short rest in the rematch against the Spirit on June 21.
Long will make her second consecutive appearance in USWNT camp, while Morgan returns from injury, and Heath from playing abroad for Paris Saint-Germain.
Morgan's availability will depend on a medical evaluation and performance testing.
Thorns defenders Nikki Marshall and Rachel Van Hollebeke were not called into camp. Van Hollebeke continues to recover from an injury suffered April 10 against China and has yet to be available for the Thorns.

Ellis Names 26 Players for Pair of June Matches against France
CHICAGO (June 2, 2014) - U.S. Women's National Team head coach Jill Ellis has named 26 players to the training camp roster in preparation for two games against France - currently ranked fourth in the world by FIFA - on June 14 at Raymond James Stadium in Tampa, Florida, and June 19 at Rentschler Field in East Hartford, Connecticut. Both games kick off at 7:30 p.m. ET and will be broadcast on ussoccer.com.
"Two matches against such a high-level team will give us a picture of where we are," said Ellis, who was named the eighth head coach in U.S. Women's National Team history on May 16. "Establishing how we want to play and integrating our philosophy is an important first step for a new coaching staff, but these types of matches will give us a wonderful opportunity to build on and keep testing out the player pool."
Several players return to the roster after extended absences ranging from two months in the case of Kristie Mewis, who has recovered from an ankle injury, to much longer in the case of forward Alex Morgan and midfielder Shannon Boxx.
Boxx, who has 186 caps and 27 goals, is coming in for training and evaluation only and will not play in the matches as she mounts her comeback after having a daughter in late February. A three-time Olympic gold medalist, Boxx makes her return to the roster for the first time since March of 2013 at the Algarve Cup.
The availability of Morgan for the matches will be determined pending an evaluation by the team's medical and performance staff of her progression toward international play. Morgan, who is at the tail end of her recovery from an ankle injury, has 44 goals in 70 matches, but has not appeared for the USA since November of 2013.
The roster features 25 players currently signed with National Women's Soccer League clubs as Christen Press, Whitney Engen and Meghan Klingenberg have returned to the league after helping Tyresö of Sweden to the brink of the UEFA Women's Champions League title. Tobin Heath's French league season came to a close on June 1, but her club will play in the French Cup Final on June 7 against Olympique Lyon. Forward Sarah Hagen will complete her highly successful run with Bayern Munich on June 8 and then return to make her NWSL debut for FC Kansas City. The only non-professional on the roster is rising college senior Morgan Brian from Virginia.
Jill Ellis will name 18 players from the 26-woman roster to suit up for each match.
Portland Thorns FC midfielder Allie Long gets her second WNT call-up after earning her first cap against Canada on May 8 in Winnipeg.
