Jozy Altidore will miss the Copa America Centenario due to a Grade 2 hamstring strain picked up in Toronto FC’s 4-3 loss to the Vancouver Whitecaps, which should rule him out for six to eight weeks. In the 35th minute the striker appeared to pull up attempting a penalty kick, which was saved by Vancouver keeper David Ousted. Altidore was subbed out three minutes later.

Altidore had provided strong contributions for the team after preseason hamstring issues, even though he has yet to get on the scoresheet this season. This is his fourth hamstring injury in the past two years. “There are so many factors that can lead into these types of situations,” head coach Greg Vanney told the Toronto Sun. “We’ve looked at a number of things. We’ll continue to seek those things out.”

Toronto FC teammate Marco Delgado was not in the squad due a hamstring injury from the previous week’s victory over FC Dallas. Toronto next host New York City FC on Wednesday.

Fabian Johnson joined the U.S. men's national team training camp on Sunday having sat out of Borussia Monchengladbach’s last three games due to a groin injury. Sunday’s 2-0 Darmstadt clinched fourth place for the Foals.

Brek Shea had to be subbed out of Orlando City’s 2-1 loss to Sporting Kansas City on Saturday in the 65th minute with what appeared to be a back injury. "This sub was due to an injury," Orlando City assistant coach Mark Waston told the Orlando Sentinel. "He had a little bit of treatment at the half and was just struggling. He went down again shortly before he came off, and he just couldn't move properly."

D.C. United goalkeeper Bill Hamid returned to normal practice last week, but remained coy on when he’ll be back from January's meniscus surgery. "I've got an indication of when I'll be back, and I know when I'll be back," Hamid told Black and Red United. "I'm excited for it. I've been patiently waiting. I've been in the background, getting my reps in, working my hardest, so once I get back on the field, I'm going to hit the ground running."
