A hamstring strain will sideline Toronto FC forward Jozy Altidore for six to eight weeks, the Major League Soccer club announced on Monday.

According to that timeline, Altidore could miss up to 11 games in all competitions, between MLS and the Amway Canadian Championship, before returning in mid-July.

Altidore, 26, suffered the injury after winning a penalty in Saturday’s 4-3 home loss to the Vancouver Whitecaps. Not only did the American forward see his penalty attempt saved by goalkeeper by David Ousted, he also pulled his hamstring in the run-up, and was quickly subbed out of the game.

Altidore has a history of hamstring problems.

A year ago, he injured his hamstring in a road match versus the New England Revolution and ended up missing two MLS games. He sat out the opening two contests of the current campaign with lingering hamstring issues.

Altidore also injured a hamstring against Jamaica in the 2011 CONCACAF Gold Cup and missed the final. He suffered another hamstring injury during the Americans’ opening game against Ghana at the 2014 World Cup opener and was sidelined for the remainder of the tournament.

Altidore told reporters during pre-season that he made a point of losing weight, changing his diet and getting in better shape in order to help him avoid similar injury problems.

His latest injury layoff is bad news for TFC and the U.S. national team who will play in the Copa America (South American championship) scheduled to take place in the United States from June 3-26.

Monday’s news comes at a time when Altidore has been lauded for his overall game (strong hold up play, and work off the ball), while also being criticized about his lack of production—he hasn’t scored a single goal in eight games (six as a starter) this season. He has 13 goals in 29 MLS games since joining the Reds last season as part of a swap deal with Premier League club Sudnerland that saw Jermain Defoe go the other way.

“You don’t wish injuries on anyone, especially teammates,” Toronto and U.S. captain Michael Bradley said after Saturday’s game. “We wait to see what comes of this and go from there.”

Altidore’s prolonged absence will likely give Canadian forward Mo Babouli a chance to earn some regular playing time.

Toronto hosts New York City FC on Wednesday and the Columbus Crew on Saturday.
