After missing the first two games of the Desert Diamond Cup, Chris Tierney was a full participant in today's training session, according to New England Revolution staff writer and online host Jeff Lemieux.
With Tierney sidelined with a minor injury, trialists Jeb Brovsky and David Addy were given extended looks at the left back position. Brovsky was most recently with New York City FC while Addy last played for Waasland-Beveren of Belgium.
Donnie Smith, who's another option at left back, has also been dealing with a minor injury.
