Midfielder Roger Torres underwent what the Union term "successful" surgery Friday morning after sustaining a medial collateral ligament sprain and minor meniscus damage in his left knee.

The club announced Torres, a 20-year-old Colombian, is expected to miss six-to-eight weeks.

Torres, who has scored three goals and logged nine assists since joining the Union in 2010, sustained the injury Monday while helping the Union to a 4-2 win over New England in a reserve-league match.

That's all the information the Union provided.

Wednesday, Union manager Peter Nowak said he preferred not to set a timetable for Torres' return. Instead, he texted me saying, "We will most probably (know) on Friday."

While MCL sprains don't always require surgery, this could be a sign that the Union would prefer not to play around with Torres' injury and would rather have him guaranteed to return to the lineup.
