Sale Sharks wing Denny Solomona has been retained by Eddie Jones for England's trip to Argentina, although he remains a doubt for the two-Test series.
Solomona suffered a foot injury during a recent training camp in Brighton and will be assessed by England's medical staff ahead of the trip to South America.
Harlequins wing Marland Yarde also met up with the touring party on Monday, and has been included in the squad as cover for the cross-code star.
There is no place in the travelling squad for Northampton back row Tom Wood, though, after he was sent off for stamping during Northampton Saints' Champions Cup playoff win over Stade Francais on Friday.
Wood, who has won 50 caps for his country, was listed as one of 27 players ruled out of the tour due to injury, suspension or British & Irish Lions commitments.
"He had an error of judgement. He did something silly, and now he pays the price," Jones said on Sunday.
"Whenever you make contact with someone's head, you will be in trouble."
Wood's disciplinary woe has opened the door for uncapped Zimbabwe-born Exeter flanker Don Armand, who was man of the match in the Chiefs' Aviva Premiership final win over Wasps on Saturday.
Meanwhile, Blues fly-half Piers Francis -- who is set to join Northampton next season -- will join up with the tourists for the first time in Buenos Aires.
"I'm really excited about this Test series in Argentina. It is a big opportunity for this group and we are going out there to win 2-0," Jones said in a statement released by the RFU.
"The players who have been in camp over the last few weeks have done extremely well and the win against a Barbarians team full of top internationals yesterday is testament to the hard work they have put in.
"We are looking forward to a good week of preparation in London before we depart this weekend."
Forwards: Armand, Collier, B. Curry, T. Curry, Ewels, Genge, Hartley, Hughes, Isiekwe, Launchbury, Mullan, Robshaw, Schonert, Taylor, Underhill, Williams, Wilson.
